Well after the lug nut incident (https://acurazine.com/forums/ramblings-12/tahoe-new-years-165027/) I finally got around to doing my brakes today, rotors and pads all the way around, Painted the rear calipers too. I have also run into a problem at 1 Corner which you can see at the end, which i'm not sure how to solve.

Disclaimer: These are merely my suggestions on how to replace your brakes, I am not a professional and this should only be taken as advice. I will not be held liable for anything you mess up as a result from following these directions.

1.Remove screws from rotors, Impact driver will make this possible.




2. Remove the Caliper bolts (12mm) pictured here. Use a wrench to stop the pins from rotating. Swing caliper away and rest of control arm.




3. Remove the caliper bracket bolts (14mm)



4. Use 2 8X1.25 bolts to push to rotor off the hub.



5. Clean up the hub a little with a wire brush. Then at the bottom of the hub rotate the little spike wheel up until it is fully retracted, this is so the e-brake shoes do not rub.





6. Install new rotor. Replace those screws if you wish, use lots of anti seize. If you use the screws it really helps when you dialing in the ebrake shoes. There is a little rubber plug that you have to remove from the old rotors. Once your new one is screwed on there is a little access hole that lets you adjust the spikey ebrake adjuster. This time you want to turn the spike wheel towards the ground until there is friction against the rotors, then turn it 6 clicks up. Replace the rubber plug.





7. With that all done, you want to lubricate the slider pins on the caliper bracket. Hold the rubber boot at the bottom and pull the pin up. Give it a little bit of grease. Push it back down so the boot full seats. Bolt up the caliper bracket to 41 ft-lbs.



8. On the caliper bracket there should be a metal clip on the top and bottom that the pads sit on. Lube those with the little packet of grease that comes with the pads, use sparingly. Remove the shims from the back of the pads and spread the grease over the back of the pad. Replace shim, grease back of shim. Slide the pads into the caliper bracket.
















9. Prepare the caliper, clean around the seal with a toothbrush to remove all the crud. The grease the part of the piston that is exposed with the same grease as you used on the pins. Use a piston compressor tool to reset the piston in its bore. Slide the caliper over the pads and install the 2 12mm bolts with anti seize and torque to 17ft-lbs.
















You can repeat these for all 4 if you have an AT for those of us with Brembos Read on.

1. Remove those danged screws with the impact driver again.
2. Turn the wheel towards you for better access, drive out the pins with a 3.5mm punch.





3. Pull pads out with vice grips. Clean caliper interior with tooth brush. Using a differnt piston compressor reset all 4 pistons in their bore.





4.Remove the brake line bracket on the spindle, 2 10mm bolts. Remove the caliper bolts on the back 2 20mm bolts. Hang the caliper on a coat hanger from the upper control arm.





5. Use the 2 8x1.25 bolts again to pull the rotor from the hub. Replace the rotor, put the 2 screws back in with anti-seize.



6. Re attach the caliper, anti-seize the bolts and torque to 125 ft-lbs. I forgot to take pic.

7. Grease the pads,, shims. Make sure you line up all the arrows with the direction of wheel motion.







8. Slide the pads back into the caliper. Slide the first pin through and punch back into place. Slip the spring under the one you just installed and hold the bottom part down while you slide the second pin through the bottom, and punch into place. It should look like this.



9. GO HAVE A BEER you just did you BRAKES. P.S. Torgue all your lugs to 81ft-lbs.

My dilema happened on the drivers side from caliper. The lower caliper bolt was cross thread from the factory or dealer. I'm still not sure how this is going to get fixed but i'm not happy. here's some pics.

 

That is really good info......

I am very glad that i did not replace my Brembo pads with OEM...

Ceramic pads are about 1000X cleaner no brake dust at all...

You have problems with that on yours?

Thanks for the walkthrough very nice

 

Ya I get the dusting, but I get OEM parts at cost so the price comparison is a tough point for me. Also I plan to sell the car as soon as the 09 comes out so longevity and such was less of a concern.

 

Nice!

One question, what rotors did you use? OEM?

Thanks and great DIY!

 

yep its all OEM.

 

Mods: maybe we could add this to the garage?

 

Nice. I changed the front brakes in my AT. I had to drill out the retaining screws... I am wondering if I need to buy the brake shims for the rears, or if I can just reuse the old ones. They cost 80% of the rear set that contains pads and shims... About 20 bux too much if you ask me.

Good Job Dougler.

 

I jus changed my Rear rotors yesterday took 30 minutes , so easy.

 

Wow.... unless you re-thread that caliper don't drive. You are missing a good 4 to 5 threads which is basically what the end of the bolt holds on to. More than likely the threads in the caliper are fine and the bolt is just messed up b/c the caliper metal is stronger than the bolt. If the threads are good just replace the bolt and torque it down to spec. Don't drive the car like you have it.

 

Some comments from 01tl4tl Regarding my work. I think he makes pretty good points about the use of brake grease on the caliper piston. In the future I would advise following his instructions regarding that.

 

Excelerate, thanks for the tips. What actually happened is someone over tightened the bolt and it pulled the threads out of the aluminum caliper, when I removed the bolt the metal that was loged in the threads of the bolt and basically finished off the threads in the caliper.

I was able to pick the aluminum from the bolt threads with a small file, I cleaned it up with a wire brush on a dremel tool, the bolt is about as good as new.

The threads in the caliper were in bad shape, Also due to the weird thread pitch buying an off the shelf tap & dye was not possible. The bolt is an M14 X 150mm for those counting, not standard fare at local automotive shops and dealers are closed sunday. Lucky for me my best friend is a CNC/ Tool and dye maker, who has a key to his shop. Even luckier for me, we were able to turn up the correct tap from their rather large selection, I had him tap the caliper for me as he uses that shit all the time and I didn't want to risk finishing it off myself. The tap re threaded it like butter, bolt went in like new and is torqued to factor specifications at 125ft-lbs for those counting. I just drove 200km and everything feels great.

After doing the bed in procedure the brakes stop pretty decent but will get better with some more miles on them.

 

Dougler.. do you drive in the snow alot? Looks like a lot of salt-snow corrosion!

Nice write up - thanks!

 

I live in canada, we use tons of salt/sand on the roads in the winter, Especially where I go to school because the temperature is always hovering around 2c and -10c there is alot of melting and flash freezing over night so they lay out the salt pretty hardcore in that area. It is known as I'm told by locals as the black ice capital of canada.

 

Where did you get the dual piston spreader for the brembo's? I cant find anything close to it in the snapon, mac, or matco tool catalogs.

 

www.princessauto.com
It was 20 bucks, they're a quickly growing chain here in Canada, they have everything and most of their stuff has lifetime garuntee without receipt! Sadly their website blows! you'll have to look for the online catalogue (pdf) and page through it to find what your looking for. I'm pretty sure they do mail order. Acura sells it as well but they wanted like 154 bucks and that's @ cost.

 

great write up

 

Thanks for this. Just did the rear pads and rotors. Had to drill out the rotor screws which was kind of a pain....then one drum brake pins broke when I was pulling off the rotor...quick trip to the dealer to get the pin and all was good. Put it all together and all was good. The pictures helped a lot. Thanks

 

great write up ... thanks for the pics this is really helpful

 

wow! awesome write-up man I was a bit intimidated to replace my rotors unassisted before, but thanks to all the details you included I think I might give it a shot.

 

It would have also been a good idea to service the rear caliper slide pins. These are the typical failure place on a single or dual piston floating caliper. Simply pull the pin out (do them one at a time), clean it and the pin-bore, relube both, and reinstall.

When a caliper pin siezes up, the outer brake pad ceases to function on that wheel. You are left with all the work being done by the inner brake pad, which wears at an accelerated rate. This also puts excessive stress on that wheel bearing cause it's the only thing left resisting the caliper pistons force.

Great writeup nonetheless...

 

2 years old thread...lol

This thread should have been in 3G TL Garage.

 

Excellent write up and pictures! Thanks.

 

I actually do do that as part of any brake service, I must have forgotten to mention it though. Living in Canada with all the salt on the roads it's important to service those rear calipers more frequently.

edit:

I knew I mentioned something about those dang sliders.

 

nice write up thanks for sharing!

 

 

Thanks for the fantastic posting. Its guys like you that save us from getting killed at a dealer.

 

Is it OK if the Parking brake is engaged when changing the rear rotors? Ive already removed the rear rotors (with the parking brake engaged), and now im having a hard time putting the new rotors on. It seems like it would make sense that the new rotors wouldnt want to go on when the ebrake is engaged or at least it would be impossible to get the parking brake to the same level of force it was at simply by rotating the spike wheel

 

Also, I stripped one of the two rotor screws and ended up drilling it out. The only problem is that when I was driliing I ruined the threads on the piece the screw goes into. Is this a problem or should I be fine with just one screw?

 

Exact same thing just happened to me, except ..... I wasn't so lucky to be able to re-cut the threads. There was nothing to be re-cut. I had a few ideas to fix it, like: cut a bigger thread and use a helicoil or just use a bigger screw and drill out the matching hole to except the bigger screw. Any other way to fix it? What do you guys think would be the best thing to do?

 

You don't need the retaining screws for the rotors. They are there as part of the process when building your car to hold the rotor in place before the caliper is installed. They are not needed now to hold the rotor.

 

Took me a while before I realized this was for a MT change job.

 

In answer to rear brakes and park brake ON,
the park brakes are a mini set of drum brakes that live inside the rear rotor- see that wide center hub?- thats the drum for the brake shoes to press against.

It should have been difficult to remove the rotor with them on, or the park brakes are very worn from driving off with them On, of they are horribly out of adjustment

MUST release the park brakes to install the new rotors- then check and adjust them to fit the new rotor per the book for your type -pull handle or foot pedal
May need to adjust them again after everything gets used to each other

New pads and rotors may take up to 500 miles of regular driving to get all the micro sized hills and valleys to wear into each other and get 100% contact while in use

NOTE: It has been found that several pad makers are/were using the wrong backing plate for the rear pads. It has 3 raised tabs on the back of the inner pad
Should only be 2, one on each end (one secures the squeeler tab the other is not used)
If there is a 3rd tab in the top center of the pad- it will contact the caliper piston and cause the pad to go in crooked against the rotor when brakes applied!!!
Applies to gen2 and 3

Easy check is look under the car at rear rotors- if half the width is rusty and other half shiny- guess what!
Can be fixed by grinding off the offending center tab- flush

Check all new pads for this problem before install (if not OE pads), and check the rotors on any rear brake job done in the past for that rust/shine situation

Real Techs: please check this when you see a TL or CL...a peek at the inner side of rear rotor takes seconds and can save lives
hawk rb and several others all used the same backing plate part number- companies I found were notified and some have made the change/correction

That pad back is actually for an RL which has a different park brake system and needs the 3rd tab to operate it---
Im guessing that somewhere along the line some years ago at a brake company:
an assistant looked up a part number for acura pad plates- put it in the computer system and the next place looked up info from them,,,it went on and on with incorrect info
GIGO!! garbage in garbage out- computer only as good as its programmer

 

I have seen those stripped bolts - its from using an air gun to blast the bolts on - instead of their exact torque settings
non brembo cars bolts are under 60 ft lbs,, while an air gun will provide 120
b

 

Do new front rotors need to be lathed before install? Just talked to a coworker about my weekend project of new pads and rotors upfront and new pads in back and he mentioned this. And, now I am paranoid. This is for a 05 MT.

Thanks.

 

Absolutely not...

Though I do find it interesting that the pictures above show new OEM rotors are completely painted silver (even the friction surface)...

 

I have the same problem about stripping the screws holding the rotor on. Anyone know what size drill bit I need to use to get them out without damage??? HELP

 

I ran into the same issue with the rotor screws on one side and happened to have a screw/bolt extractor set that worked well to remove the stripped screw.

 

I hate to bring up an old thread, one which is very useful btw, but the caliper bolts on the Brembo fronts are not 20mm, they are 19mm. Just an fyi as I had to make a trip to the store for a new socket haha.

Great write-up though, it really gave me the confidence to do my own brakes.

Thanks.

 

Great details and pictures; I'll definitely look out for the issues you pointed out.

 

Maybe mine was made on opposite day, but I had to rotate mine all the way down in order for the rotors to go on.
