sticking caliper?
 
i was driving the other day and started to smell burning rubber. it went away after 10 mins so i just figured it was the car in front of me. i go to make a left turn and push the break down the whole front end got really squirrely like i was slipping on ice. i let off the break and it started pulling real hard to the right. to go straight i had to have the wheel turned 45*. i drove it for another hour or so and the only time it pulled was when i hit the breaks and the pulling would go away after 10 mins. then it just kinda stopped doing it. drove it another hour without a problem. any suggestions on what happened and what to look for?

My passenger side rear caliper seized and smelled pretty bad. Apparently its pretty common especially if the Jeep has been sitting for awhile. A trip to the mechanic, a new caliper, and a machined disc and it was back to new.

mine does sit around quite a bit. any ideas on why it does that?

I think it's because one got stuck on half way so it burns and smells and when you hit the brakes, only the other side applies properly so then it pulls on the other direction.. I'm experiencing the same problem. I'm 95% percent sure it's a bad caliper.

By seizing I mean it gripped when I pressed the brake, but didn't release. It was stuck in the 'braking' position.

have you pulled anything apart to take a look at it? is it possible for air to get in the line somehow and cause problems? im gonna be out of town for the next month for work so i wont be able to mess with it. if you figure anything out would you let me know.


i didnt see that you posted how it got fixed. have you had any problems since getting it fixed?

Happened to me. I pumped the brakes while my dad tapped on the caliper and shot it brake cleaner. Havnt had a problem yet since then

Its also pretty common that the rubber hose deteriorates on the inside. This allows the fluid to go through one way when you push on the pedal and since there is no pressure pushing back, it gets trapped and won't release the brake. It slowly releases the pressure and the brake frees up. Mine did that on the front driver's side. Replaced the hose and no more problems. It really got hot in stop and go traffic.

Sorry I can't help you there. I didn't have the skill or the time to trouble shoot it myself so I let my mechanic deal with it. He had said that it had probably been creeping closer to locking up for months, then finally became apparent since I got new pads and rotors. He did say that on his TJ that sat for a year, the front two brakes locked up on the highway and sent him spinning.

Everyone told me it was the caliper, too. Which it might very well be. How I troubleshot it: Jacked the affected wheel up. Took the tire off. Pumped the brakes until the rotor would not turn. I unscrewed the bleed screw. Rotor turned so it was the hose. If the rotor had not turned it would have been the caliper. Trouble shooting is the key. Don't just go replacing parts. Either way, you will have to bleed the brakes anyways once you fix it.

i think ill have to give that a try. thanks for the info. i was gonna put my hands on it before i took it in just to see if i could figure it out. so what was the fix for you? id like to try and learn from everybody and not overlook anything that could be causing the problem.

Fix for me was to replace the hose. If it turns out to be the caliper, then the fix would be replace it. The hose was something like 18 bucks or so at AutoZone.

my local auto parts guy just told me the same process. I called to purchase a new caliper and he asked why? I told him what it was doing and he explained this process to me for troubleshooting. :punk:

Also if you replace the caliper or hose on one side replace it on the other side.

I've had my wrangler for just over a week now, and I've noticed the same thing... grabby brakes. I'm glad I noticed this thread, Thanks guyz! Y-all prolly saved me a bunch o'$$s

wasurfer86 06-07-2011 11:24 AM

by unscrewing the bleed screw will that cause break fluid to leak out?
