  • Sticking caliper or....???

    Thought I'd put this here instead of Facebook where uninformed newbies might chime in.

    A few months ago, I drove my truck 30+ miles and the right front wheel starting "sticking." And by that I mean I would be at a light, lift my foot off the brake, and the car wouldn't move until i pressed the gas...after clunk in the front right.

    After some internet research, it has all the signs of a caliper piston sticking on the rotor. Finally had a chance to have my mechanic look at it the other day and he says the piston is not sticking...the brake is functioning normally...and that on a test drive, it did not fail in any way.

    So, question is...what else could it be (front diff?) and why did it only occur after a long drive? I've taken a few short trips in past few days and it does not stick.

    thanks

    Assuming he checked the guide pins on the caliper correct? CV axle starting to go out maybe?

      He's a good mechanic so I'm trusting he checked the pins. The CV axle is another story. Would that get worse with the more distant I drive? Because I'm getting no symptoms on short drives. thx.

        What about the brake hose itself?

        That can cause the same symptoms as a sticking caliper, but only sometimes shows itself when compressing the piston back into the caliper. If they are original, I would suggest replacing them both (and the rear one going down to the axle) just for piece of mind. I can't imagine it being more than $60 for three OE style brake hoses.

          Thanks, Morgan. I think that's the way to go.

        So, i took the truck out today (perfect weather) and start it up. This is the first time since I had it at the shop. Brake light is now and and I'm getting a click at the pedal when I first press the brake. (and each time I return to it). WTF. (meanwhile, caliper did not stick at all during drive today...about 10 miles).
