I've been having some problems with vibration, noise and pulsating brakes with my blazer for a while. Since I replaced the front brakes, the problem hasn't improved much. Its mostly because the back e-brakes need to be grinded down more and the brake lines need to be bled. Hopefully once I finish those things, my brake problems will be over with. If not, it'll be time to take it into a shop. x_x Anyway, I did some more front brake work on the blazer last week. I cleaned off the rest of the leftover grease from the calipers, sprayed disc quiet on the brake pads to stop the annoying squeaking noise (which it did take care of) and I cleaned and liberally re-greased the caliper pins and rubber boots they fit into. Disc quiet works by acting as a sticky adhesive on the back plate of the brake pad. It causes the brake pads to stick to the caliper so that when the brake pressure is released, the caliper pulls the brake pads away from the rotor and holds them in place so they don't bang around or continue to slightly rub against the rotor while you are driving. Heres a pic of the sprayed on disc brake quiet on the brake pads. Always remember to spray brakleen on the sides of the pads or the metal nub ends if you spray them by accident. The brake pads put back on, with grease applied to the connecting points. This is the caliper bolt pin I mentioned in my other blog post for the front brake job. I wiped it down and mostly cleaned it up. Here it is greased up and ready to go back into the caliper/brake pad mounting piece. And if anyone is interested, here is a pic of the hand goop that I use to clean the grease, dirt, oil and grime off my hands. This crap works amazingly well.
