Hi I am new to this forum and was wondering if anyone can assist me on information on how to bleed the brakeline for a 2009 TSX... I took the tire out on the driver side opened the valve and bleed it out but there was no air after putting everything back on it seems the brakes are not stiff which they should because the pads were changed the same day (Yesterday)

iCrap

did you use a bleeding device? you cant just open the thing

z643167z

no i didnt, i was using a quarter inch

A quarter inch what? Check youtube for ways to bleed your brakes. There are cheap methods of using a bottle (to create vacuum) and a clear plastic hose. Or you could get a device like the mityvac.

Yeah that's why it didn't work... you don't just open it and the air comes out. You need to either use the bottle method like xtc said or buy a bleeder kit. i got one from harbor freight (lol) that actually worked really well.

Once air gets in the brake system you need to bleed all four brake calipers and be sure to follow the manufacture's bleeding sequence and brake fluid type.

i bleeded the front to brakes... it is braking better now....

iCrap

does your pedal get progressivly softer as you brake?

z643167z

it was before but now that i did both the front valves it seems to be better.. I reason i had to do this was because i changed my brake pads in the front and while doing so i accidentally unscrewed the brake-line screw instead of the caliper screw. =/

^lol nice. Lesson learned

Glad to hear your brakes aren't spongey anymore.

No offense, but after reading your posts on this subject the best advice I can give you is to find a good indy mechanic and trust him to do it correctly !! Brakes are too important to trust that you've done it right !! JMO.

^ I agree. You should get a repair manual, its in this case a life saver... lol. It will pay for itself many times over. You should ask a friend who has experience to coach you for the very first time when working on brakes, suspension, or anything you're not sure of.

Critical information is missing...
1) Did you only replace the brake pads?
2) Did you compress the piston's without opening the bleeder valve? If YES , then there is no reason to bleed the brakes.


Most new pads usually have a spongy feeling for the first day or so. Once bedded the spongy feeling goes away.


If for whatever reason you open the brake hydraulic system, this is the method to bleed the air from lines. I recommend you use the Honda/Acura brake fluid. It is better quality from anything you get from the local parts stores.


1) Make sure the master cylinder reservoir is full.
2) Attached a clear plastic hose to the bleeder valve. This is needed to check for air bubbles & keep the fluid contained.
3) Have someone assist you by pumping the brake pedal.
4) Start at the LEFT FRONT wheel. Have the assistance pump the brake pedal a few times then hold the pedal down. Crack open the bleeder valve make sure the assistance keep applying pressure to the pedal as it moves downward, not letting up until instructed to do so. Close the bleeder valve once the fluid stop flowing. Then instruct the assistance to release the pedal. Repeat the process a few time till there is no air bubbles present . Then move to the RIGHT FRONT, RIGHT REAR ending at the LEFT REAR.
**Be sure to check the master cylinder reservoir level & top off after each calipers are bled**

FYI: There is no reason to open the brake line(s) if you are just doing a routine brake service. Brake services are normally done without bleeding the brakes. They can be but not require.

The only time you bleed the brakes is if air got into the brakes system some how. If there was a leak in the brake system ; a brake component failure (needing to disconnect the brake line to replace the part); brake flush (preventive maintenance)... etc.

Also do not push on the brake pedal while the caliper is off of the rotor.

guys stop helping him, it's soupi!

Thanks for your advice, I was changing my brake pads, and accidentally opened the middle screw which leaked out the brake fluid only a little bit leaked out...

When bleeding the front to brakes I noticed there wasnt any air.
