Exclamation Brake Probelm

Hey guys,
I'm having some problem with my breaks.
it has happened a couple of times so far..
i feel the breaks on front right lock up and are not released.
while driving it smells like burnt electric cable. it also drags to the right and wont accelerate as it should. and applying breaks sways my wrangler all over.. need to do a lot of corrective steering..
so far i've noticed that it works fine after i park it for a while..
once it happened on the throughway and it was ok after bout 20-30 minutes of driving.. tat that time i didnt realize it was my break that was acting up..
what should i check for??
any tips would be really appretiated.
thanks..

Been in a lot of deep water? Could be callipers and/or master cyl.....I had a simular problem in my old 72 vette after a flood... was the callipers in my case, either way the brake fluid is building up and not making it back to it's "resting" place

I believe the way to check is to get the brakes to lock up. Then pull the wheel and crack the bleeder. If the brake still stays locked up then the caliper is seized. You should also check your pads and rotor to see if there is any grease built up on it that would cause the brakes to lock up.

Sounds like a caliper holding up. The pads could be hanging up on the caliper but from what you describe sounds like the piston is sticking.

Probably seized Caliper.
I just had to do my front & rear calipers last weekend since they were seized & smoking a little. The caliper piston on mine where seized (corrosion & mud) from over the years.

One good way to tell is if removing the brake calipers & brake pads, use a c-clamp and try pushing the caliper piston back into the caliper as if you were putting new pads on. If it's hard to turn, like you really have to make it turn or wrench it then seized piston.
Also make sure to remove the master cylinder resevoir cap before pushing piston back in.

Sound like a bad brake hose. A piece of the inner lining of the rubber hose can come loose and plug the hose and not let fluid back out of the caliper.

All of these responses could be your problem. I agree with getting it to lock up and then opening the bleeder valve on the caliper. If the brake releases then the problem is not the caliper and you should look upstream towards the master and find what is keeping the fluid from returning to the master. Most likely will be the flexible hoses others have mentioned.

Just my 10cents.
