Brakes Sticking Caliper?

stykthyn · Oct 11, 2014

Just took the car out for the first real drive in almost a year. Car started smelling hot about a block from the house. Thermostat said the engine was good so I got home and was greeted by smoke pouring out of the passenger wheel well. Obviously the caliper is stuck or hanging. It's a 99 pbr twin piston unit. Waiting for it to cool down for a couple hours before I pull the wheel off, but how screwed am I? Any chance pulling the.caliper abd collapsing the pistons will fix this?

I had this happen about a year ago. Not as bad of a circumstance as you, but I noticed that my car would hold itself on a small hill.

I pulled the caliper apart, removed all the seals, and used a piston hone to clean up the inside of the piston bore. Cleaned it well, and reassembled. No problems as of yet.

My calipers came from a junkyard, I think they had moisture inside them that causes some corrosion.

Guess I won't know for sure until I get it off the car. Getting late now so probably won't happen until tomorrow.

If it was a stuck caliaper make shure u check out your rotor. Does it have a blue color with waves in it(overheated). I've never dealt with dual pistons.. Check your slider pins, They can dry up or get a little rust on them if it was sitting that long.

Well the rotor is fine. No bLueing or warping. The caliper is in need of a rebuild. Piston seals are shot and one piston is frozen. I collapsed both and pumped the brake. Only one side moved.

This may be the problem.

You're killing me

take some emery and hit the inside of the caliper and the piston so you don't tear the new seal.

Piston Isn't moving. Tried soaking in parts cleaner and using compressed air to get it out but it won't budge. Reman Unit from A1 is around 45 dollars. May hit the jy abd see if there is a v6 sn laying around abd just take those.

I'd just buy a reman, it's not like those calipers are powder coated or are anything special.

Mustang5L5 · Oct 14, 2014

Those calipers are notorious for sticking. It's a common issue, especially if the car sits.

A reman is about $40. Not a big deal considering there i a chance a junkyard V6 has frozen calipers too.

Don't listen to these guys. That brake caliper has ALL KINDS of life left to it.

Perhaps even a destiny.

Omg noobz that's badass

Even Perp Boys will be better than the junk yard, and the price is not bad. My paint is worth more than cheap, used calipers.

Noobz347 · Oct 14, 2014

I would also like to point out that it IS on topic.

7991LXnSHO · Oct 14, 2014

I am already having nightmares about bad brakes. Thanks a lot!

Did you lock out the one piston that does move and press the brake pedal to get the other to move. When there is no resistance on the caliper, the piston that the fluid passes first will move before the other even thinks about it.

Micheal Nadeau · Oct 14, 2014

Are the piston seals "shot" because you pressed the piston out of the caliper and the brake fluid leaked out behind it......? Because the one piston is no longer seated in the caliper.

7991LXnSHO · Oct 15, 2014

If a (mostly) non compressing fluid - brake fluid - at a high PSI will not move it, highly compressible air at a much lower pressure will not move it either.

I was logging on to ask if you kept the other piston in place with a C clamp, but someone pretty much beat me to it.

The guys warned about the used ones I have setting around. They are likely to be stuck, and to just go with remanufactured ones at the cost over doing it myself like a drum brake cylinder.

No. Seals overheated and melted.
