The rear brake caliper piston is stuck when i try to turn it. The rubber boot tore off and now the rest of the boot seems to be jammed inside the caliper. Becaue the boot was ripped off the piston is getting rusted.
This is the second time this happened, i changed the boot about a year ago, and now again it ripped. Should i just leave the piston without a boot in the future ? Anyone else had this problem? I can't change pads due to this problem, i even sprayed some lubricant hoping the piston would turn better but no use.

 

get a new caliper. Its sounds like its frozen

 

Whtmax'01,

We have had the very similar issues with the car ... lol. Do you know the production date of your car?

Here's some info I collected whne I recently changed my rear driver side caliper you might find it useful:

I think if I had to do it again I'd maybe get autozone, pepboys or something local for replacement, because you have to pay to ship back the core to get back your deposit.

They seem pretty much the same. I must say though the nissan one looked new even though it was remanufactured. It was also greenish, like when the car was brand new. My brakes are painted silver so it didnt matter.

 

Woosh, not sure when the car was made, i bought it in october of 2000 and it lists as 2001 model. A while back i bought a piston kit for the caliper and replaced all the seals as well as the boot. It seems that the boot rips from drying out because it ripped at same location as last time at the flexing point. I remember a while back few other people had this problem with their brake pistons, perhaps its the poor rubber quality, other than that i cant think of anything else that would cause the boot to rip.

 

Hey man get some wd 40 or silicone lubricant and spray on the boot before you try and turn the caliper---those calipers get kinda hard sometimes and the lubricant will help the boot from not taring

 

same thing... clean it really good with a real good lubricant and you are good to go. I did to my car and no problems ......

 

I did clean it but piece of rubber is stuck inside caliper and is rubbing against the piston, should i take the piston off completely and take the rest of rubber piece out or just leave in there and spray silicone ?

 

you can take the pistonout and put it back on.. no harm done.. just remember to bleed the brakes after you are done.

 

It does seem like a simple setup. The piston flew out on mine once when my friend stepped on the brake while it was off the rotor. I got the piston back in but had to bleed the system.

It seemed like all the rear caliper was, is the chrome cap (looks like a chrome shot gun shell) and threaded rod in the center of the caliper. Then there is actually a groove near the top of the piston that rubber sleeve drops into.

Only thing I didn't get is what holds the other end of the rubber to the inside of the caliper cylinder. Is it glued ?

 

To prevent rear caliper/piston from seizing - use hand brake occasionally

 

Igzy,

I don't think that theory holds water. I live in NYC and use my parking brake almost everywhere I park to prevent ppl from trying to push the car in park.

I still ended up with a seized rear caliper.

 

Today, i removed both rear calipers and put new seals and piston boots. Due to the wear of the boots the piston was badly corroded. I did what manual doesn't recommend which was to grind of the rust and polished the piston. It seems the rust ate through the chrome plating. I put a lot of grease on the piston before installing it into caliper. Everything seems to work fine now, until next year ill prob have to do this again. Ill have pictures soon of how my piston looked.
Tried to bleed to the brakes, but brakes feel mushy still, anyone know do i have to bleed the fronts too even though i didnt even touch them?

 

Yes, you have to bleed all of them. Passenger rear, driver side rear, passenger front, driver front.

Get yourself a trusty assistant. Make sure they pump hold until u tell them to let go, warn them not to release when you open cause the pedal feels weird when you open the bleeder bolt. I used fishtank hose on the bleeder bolt head, fits perfect.

 

Using parking brake doesn’t help. I use it all the time and my rear brake seized anyway.

 

Hm, interesting, I use mine every time I park and no probs... I have 70K+ on original brakes and nothing seized (I checked 2 days ago)...
