Seems like my rear caliper piston is sticking, need c clamps to push it in and it doesn’t release completely after applying and releasing the brake pedal. So the question is, is the piston binding on the bore, or is my brake line collapsed and not releasing pressure? Car is an 06 Tl, which doesn’t seem old enough for the brake hose to have collapsed. So yeah, fucking Honduhs, wheres the reliability at?!
are you sure it’s the piston and not the sliding pins?
Sliding pins move in easily, and out by themselves.
you can get a rebuilt rear caliper from advance auto for $66 - $20 (discount code) = $46 then get 6% off of that (fatwallet) and 1% (most credit cards) = $42 so it might just be easiest to replace.
see for code and fatwallet discount:
stupid question does the tl have a internal parking brake is it built into the caliper
definitely not a stupid question
Don’t you Honda guys have access all those cool online part schematics like us Z guys do?
Previous gens had the ebrake built into the caliper, this one has shoes inside the rotor which I loosened to make sure that wasn’t the issue.
Decided to buy a rebuilt caliper and a brake hose, came out to something silly like $60, so one of those should fix it.
simple way to tell- undo hose (or open bleeder) if it releases its in the hose
What the hell is a collapsed brake line?
Kinda like an artery of your heart. Once they wear out the internal structure fails, so when the pressure gets released (foot comes off the brake pedal) the hose collapses and doesnt let the fluid move out of the caliper effectively keeping it actuated.
Hrm. OK. Sounded weird. Things under pressure don’t really collapse. Sounds more like a plug. Either way I learned something. Never would have thought a bad hose could keep a caliper actuated.
Exactly. they dont collapse until the pressure is removed. I don’t totally believe it either as the piston should be pushed back by the square o-rings in the bore. But I suppose if the negative pressure from moving the MC piston back is greater than the force exerted by the square seals then it might be able to collapse the hose?
Seems highly unlikely on an 06.
^ This
Should either be likely on an 06? I know nothing of this subject so I’m not totally sure how long the average caliper life if. FWIW I’ve got the same problem with my 2000 Prizm and was told it’s a faulty caliper. But my brakes are due for an overhaul anyways so that’s on the to-do list.
eh. the calipers see the elements while the inside of the hose does not.
Most of the time brake hoses fail when lazy techs use vice grips on them to not let air in when disconnecting them for easier bleeding. I’ll check tonight by releasing the bleeder to see if theres a pressure build up, either way new caliper and hose will be in on thursday.
Heres a picture to demonstrate what happens when a brake hose fails
06 tl has the parking brake inside the brake disk like a little drum brake. The calipers can be pressed in with a c clamp. You should either rebuild or replace both rear calipers. On my 04 TL my pass side rear had to be rebuilt at 140k miles and my driver side rear had to be rebuilt at 160k. I dont consider that terrible at all.
Common issue on these. Buy a caliper.
