im going to be painting my rotors next week and i need to know what is the torque pressure to tighting the blots back. anyone know?

mmade22

Your painting your rotors?!?! I hope you mean calipers. Look it up in the Garage section on this site. I think it is around 80 foot pounds but don't hold me too it. Look it up.

ac08odl

calipers******

ac08odl

i cant find it i been searching since my last reply

01tl4tl

its not 80--thats for the wheel lugs

assuming standard brake calipers- not brembo-
caliper bolts on my gen2 (basically same brake caliper) are ~fronts 45 ft lbs, 18 foot pounds rear calipers
tiny bolts really and you dont want them overtight as that will rip the threads right out of the bracket- I have seen it happen
kragen.com has a help section with torque specs for the brakes

ac08odl

are you sure the fronts 45 ft lbs and 18 foot pounds rear?

avs007

You talking about the caliper bolts or the caliper bracket bolts? (Because if you are removing the rotors, you'll need to remove the caliper brackets)

The front Caliper Bolts are 37 pound ft, But the front caliper bracket bolts are 79.6 pound ft. (If you have brembos, the bracket bolts are 125 pound ft)

For the rears:

The caliper bolts are 17 pound ft, and the caliper bracket bolts are 41 pound ft.

(I pulled these numbers out of my service manual)

01tl4tl

well I guess the memory is still pretty close!
When in doubt- look it up yourself I gave a good resource

01tl4tl

Since you appear to own a torque wrench- use it to check the current factory torque before bolt removal

ac08odl

i dont get it?

ac08odl

service manual? does every car come with one one these?

Majofo

By using your torque wrench on the mounted bolt you can figure out what torque is on it currently.

avs007

No, I got it separately.

avs007

That's not entirely accurate. For example, it may be installed to 50 pound ft, but it could very well take more than 50 pound ft to remove it, because the bolt could be rusted on, etc, etc.

mmade22

Your memory was way off...lol.

80 ft pounds like I said before.

01tl4tl

thats for the bracket to knuckle bolts
the caliper to bracket bolts are much lower torque as stated above

now shall we discuss proper removal and tightening of the wheel lugs and bringing them up to 80 foot pounds?

Tripnbeats

if its brembo there are no caliper support brackets if its not brembo there are brackets. anyway on the brembo setup its 125lbs and on the standartd ones are 79.6lbs....80 wont hurt

Tripnbeats

oh and then for the bolts to hold the caliper on the bracket its 37lbs

01tl4tl

Im gen2 so they may have altered the spec by a pound or 2~
my bad-
but considering the shop tech blast them on with an air tool of some type- and I have measured them at 132-140 on a TL straight from a dealer brake job!, we are close enough. My torque wrench is old school so no .7 for me

What I do know for sure on brembo cars- do NOT touch the allen head bolts on the backside of the caliper!!!!!!!!!!
The 2 normal bolts hold the caliper to the car- the allens hold the 2 halves of the caliper together and a bunch of brake fluid comes out if you loosen them~

01tl4tl

Those familiar with my post know this one is coming:

while the wheels are off- flush the brake fluid
Book says starting at year 3- thats the end of year 2--flush the brake fluid EVERY year

simple diy- if you can paint calipers you can do this

Tripnbeats

I dont think a lb or 2 will make a diff.....so its all good.....Ive experienced the same thing where the guys just smash the bolts with guns....i flip when i catch people doing that....I always say break it down with a gun put it back together by hand.

lol yea def dont touch the allen bolts....unless you have the rebuild kit in front of u and its in ur plans to rebuild and clean them.

Majofo

I stole this from Mug's photo gallery.. Problem Solved..

01tl4tl

No one said you have to remove anything- thats why the paint kit includes tape~
Some people just paint the outer side of the caliper, maybe paint the bracket face as it sits.
Only doing whats visable
Others like to do a full spray paint job or complete coverage of parts with brush method
to ensure actual rust protection and good looks

The better job at prep and paint a few layers now you do now will keep it from getting nicked up so easily, and only need a small touch up before an azine meet.

01tl4tl

As long as you are in there- pull the pads and inspect- then grease all the appropriate places- the pads and sliders in the pic are not greased

Brakes work better when things slide as pressure is applied

Majofo

lol.. I just randomly saw this alblum in the photo gallery section and remembered this thread and the disagreements about the torque on the bolts...

I wouldn't paint the calipers unless you had the brembo's with the Acura logo on them. JMO.

ac08odl

ok can some one please tell me what pressure is it for my 2008 base tl not a type s.. im getting a lil lost here.. i just want to take off the rotors and paint the calipers.. please tell me whats the pressure of the bolts that need to be taken off.. remember all i want to do is take the rotors out..

Majofo

Have you worked on your brakes before? You don't need to take off your rotor to paint your calipers. Taking off your rotors just to paint your calipers isn't recommended and the retaining screws on the rotor can be a real PITA to remove even for a newer 3G TL like yours.


AVS, Tripn and 01tl4tl gave you the numbers already. 37 up front and 17 on the rears 80 on the wheels.

Tripnbeats

yea unless u knwo what ur playing with dont take ur rotors off the car. just leave it all in one piece...i undertsand you wanna get in the caliper n do it all nicely but just leave the inside alone....NO ONES GONNA SEE IT

01tl4tl

all you may want to do is remove the rotor----
BUT to get to them you have to remove calipers, pads, caliper brackets and finally the rotor retaining screws!!! THEN you can remove the rotor
OR
Follow the direction ON the box of caliper paint
Do the easy method as shown in pic earlier in this thread, just tape off and brush on the paint- done
No removal of critical parts beyond tire is needed then- much safer for a noob

read the owner book and learn the right way to loosen and tighten the lug nuts in a star pattern

ac08odl

yeah but i want to do spray paint...

01tl4tl

then its going to be a mess,,, and removal of the brake calipers and brackets-rotor if you are doing its center lip,
be really careful about the brake lines and not stretching or twisting them!!

I brush mine and no one has ever noticed anything but the fact they are stealthy black
You cant see them very well thru most wheels, and on the road- who is close enough to notice any imperfection?

Now if you are going to make it a trophy contendor at hot import shows- powder coat everything!

Quick Poll of actual caliper/bracket/rotor painters

Did you spray or brush? which parts?
or go all out and have them gold plated?

You sure you want to paint these calipers? I think your mileage might drop to 7mpg. And please don't paint the calipers on your "future" M3. :P

Keep a brush handy to remove rust from any affected parts. And be sure to use Loc-Tite when you begin to reinstall your brake system.

are you trying to be funny?

Just trying to lighten your mood. You're always in such a hurry to get all huffy when people don't post what you want to hear. Apparently it's not working.

But I'm serious on using Loc-Tite. That stuff works.

ac08odl

now thats what im talking about.. ty

avs007

I spray painted mine, but I still left it all on the car... I just wrapped the rotor with newspapers, and lots of masking tape around everything else.

ac08odl

really? and you didnt get no over spray? do you have pics?

01tl4tl

enough paper and tape and you can protect everything!!, do the fenders
The question is why,,, when you have a viable alternative

Maybe you already have a can of spray paint- you can spray it into a disposable cup and use a flux brush or foam paint pad to do a really nice job

I used hi temp BBQ paint-flat black- as a primer coat, sprayed into a plastic bottle, then multiple coats of duplicolor gloss black caliper paint
Engine paint also works and has many color options
