I recently bought my wife a 1998 Nissan Quest with 80K miles. The previous owner had replaced the right caliper and put on new brake pads. I didn't think much of it until I drove it a few days and the front brakes started roaring and rumbling. I pulled the wheels and checked - it seemed like they had been fairly hot and were glazed. So, I installed new rotors, Wagner pads, brake hoses, and a left caliper (the right is already new remember). Everything is new from the brake line down. This worked great for a short period of time, but now the brakes will squeal and sometimes grind, especially when they are cold. After I drive it a little bit it seems to go away (especially the grinding). I haven't pulled a wheel off yet to look at them again. Any ideas?
The rotors would be best to be swirlled finished also. Did you use brake caliper grease on all the slides and moving parts? How about the master or booster? If anyone has done anything there, sometimes the rod is adjustable and it may be off slightly. Just thinking...
I got Wagner ceramic pads and I used Caliper grease appropriately. I haven't done anything to the master cylinder or booster. I haven't thought to check the rod - I don't know if anyone has worked on it before and I'm sure it's adjustable. When you say off, do you mean by too much or too little (applying pressure all the time or having too much play). I don't understand how having too much play would cause this problem?
Too much play would not, you are correct. Just that I have seen where someone tightened it too much and it caused the brakes to be applied slightly and cause glazing and blueing. How about the backing plate? Maybe it's touching...
That makes sense. The way this acts, that may be the case - I'll check it. I don't think the backing plate is touching - I think I would hear that.
I work at a Nissan dealership in the service department. Usually that noise is caused by either the sliders or the shims. Most of the times its the shims. Maybe the non OEM calipers are missing those shims. I have found that anytime aftermarket parts are put on a Nissan there is always a problem especially when it comes to brakes. Alot of people removed those shims because the aftermarket pads are a little thicker and they think they are just an anti-rattle clip. Something to check...
The sliders are in good condition and are greased. Hmm...are you refering to shims behind the brake pads? There weren't any loose shims behind the old pads or any that came with the new pads. There is a shim that is already attached to the back of the new pad.
