Thank you for asking your question on JustAnswer.
The problem you are discribing is usually caused by sticking caliper. Replacing it will correct your issue. In most cases if you replace one, then its best to replace both sides.
New caliper, another bleeding of the lines. No change. 4 mile trip to return the core and I have the wonderful smell of hot brake pads on the right side. Truck still sits at a stop without the brakes on.
I jacked up the front end. Left wheel turns fine, right takes quite a bit of force to move it. For giggles, I cracked open the bleeder valve and closed it. Once I did that, the right wheel turns fine.
Is there a chance you could have used some contaminated brake fluid? Did you also change the hardware. Grease the pins on the hanger?
If the fluid is clean then it has to be the caliper unless the line to it from the master cylinder isnt pinched . If it was the master , it would effect both and or all 4 wheels.
With the cracking of the bleeder valve and the wheel releasing that would indicate to me the caliper is working fine. What is the "box" that sits between the master cylinder and the brakes? I see two lines coming out of the master the seem to go into this box then I believe four lines coming out of it to each brake. I'm seeing no kinks anywhere. I'll have to wait for things to cool down before taking a closer look. But could this "box" of the line coming out of it to the right front potentially be blocked such that it is a one way line?
Also, with the new caliper were top and bottom rails that snapped on to the upper and lower brackets. With these on, it took quite a bit of work and force (not abusive) to get the pads seated in their location. With these out, they slide in easily. Are these required or are they a part for certain models?
OK. Well I'm hungry and it's been a long day. We'll resume this tomorrow after work weather permitting. Being the caliper is new, I don't suspect any issue with it. However, I've known it to happen. Is there anyway I can check the caliper to eliminate as a suspect? Could there be something in the line from the proportioning valve to the caliper causing this? Can that line be removed, cleaned out, and replaced? And, I'll plan on taking the precaution of replacing all the brake fluid. Anything else you can think of sir?
There should be no restriction unless you have a pinched line. The only way to check the caliper is to squeeze it back in and see if it goes in smoothly and comes out smoothly. If the line are not pinched, and the caliper pins are clean and moving freely, I would suspect a bad caliper.
