Sil-Glyde on the pins if they have rubber boots. Anti-seize if they do not. Molykote M-77 or Sil-Glyde between pads and shims. For shoes, a dab of anti-seize where the shoe contacts the backing plate. > > Where does the shim go on disc brakes? If you mean the anti-squeal shims...on the backs of the pads. Some applications have two shims on the inner pad. The other find of shims I'm aware of go between the pad and the padss bracket. These give the pads a slippery surface to ride on as they wear towards the rotor. > > On drum brakes, you're diassembling a cheap set of relines, and > replacing them with a set of brand-new shoes.

My only experience with rear calipers that require a tool are those where the piston must be screwed back in. These all had parking brake mechanisms as part of the caliper. Do drum-in-hat type rear discs require a caliper piston tool, or can you just push those in? > > What is the difference between a fixed and a floating caliper? Floating caliper uses the force of piston(s) on only one side of the caliper to pull both inner and outer pads into contact with the rotor. The caliper must slide over to allow the outer pads to contact. Fixed calipers usually have pistons on both sides, so there is no need to enable the caliper to slide I saw a weird setup on a Nissan pickup once. The caliper itself was fixed, but the assembly was still "floating", with two pistons on just the one side. Very interesting. > > What's the prupose of a metering valve - NOT proportioning valve - on > a disc brake setup? How does one diagnose it? (HINT: If you know what > it actually IS, you are halfway to diagnosing it.) It keeps the front discs from working before the rear drums have begun to work. I suppose if you had a problem with the rear brakes not working but the fronts working fine, you'd investigate the metering valve if everything else checked out OK. How'd I score? -- Tegger

How does one diagnose it? (HINT: If you know what it > actually IS, you are halfway to diagnosing it.) RTFM...it's all in there.

Some > applications have two shims on the inner pad. Shoot!!! I thought they went between the pads and the rotors! No WONDER I keep hitting kids, trees, old ladies, etc... But, I'm racking up points like a champ!!!

What do I do?!?! What do I do?!?!
