I have a 95 Disco and the brakes have been squeeking since I got it. I read all the archives on the subject. I put the anti-squeek stuff on the rears, took off the "glaze" with sandpaper and they stopped for a couple days. They have plenty of wear left. They only squeek when the brakes are NOT pressed. I read about someone cutting out pop cans for spacers, what is that supposed to do and does it work? Does anybody have a fool proof method for getting rid of the squeeky brakes before I go crazy because I hate the dang squeeks!

get organic brake pads, the semi-metallic shit will drive you banana.
i put a set of semi-metallics on the range rover recently, and hated it since. rear went to the trash since; i hoped the front ones will wear themselves in, but no dice.

put a set of organic pads in the disco, and no sound whatsoever.

Squeeky pads are what you hear. Several minor conditions contribute. Fixing it: 1)Deal with
front whl brgs first-repack grease and tighten to spec. Reason: Any looseness here will allow wobble as wheels rotate, backing the pads away from the disc, thereby encouraging the VIBRATION OF THE PADS that is 100% of the source of the noise. 2)Remove the pads and place on the back side of them, anti-squeel PADS affixed w/ adhesive. Find at any decent parts place. Forget the anti-squeel greases/lubes or any of that crap. 3) I can't confirm that your discs are not glazed, so you have to do this: Freeway speed, exit off with no one behind you!!, and apply FULL stop/abs level emergency stop; repeat 3-5 TIMES. Discs now deglazed. Pads deglazed. All should be well. Report on progress, here. Best re, DGJ 95rr

Always replace pads with complete brake ..which should have brake shims....without it your brakes will make noise..

guess what, they make noise with shims, too.
besides, some places sell pads without shims.

i've bought a set of semi-metallic brake pads without shims at Napa, and a set of organic pads with shims from brakeco.com.

Napa gets thumbs down...

I went crazy trying to get rid on my squeals. I finally had some real progress in peace and quite dept after I did this: I took some Emory cloth and polished my pins.I then gave them a good coat on caliper grease. Everything is nice now.

what would polishing the pins do? You talking about the retaining pins?? Sounds like organic pads are the way to go. One thing I may have done differently is let the anti-squeel gunk setup before reasembly. I just spread it on and stuck it back in. Didn't make sense at the time but I didn't know any better.

Peter why would I bring up Scout shit here?

I cleaned/polished the pins because it seems that the pads were hanging up on the old dust/mud and not moving off the disc. Yes Shane The retaing pins! 1,rolleyes

OK, here's what I did and working so far (only 1 day, we'll see). I pulled the pads, used my dremel to take off the sharp edge of the pad, sanded the surface of the pad, polished the pins and clips & greased them up, put on new anti-squeek stuff and let it sit for a while to firm up a little. With the pads out I pumped the brakes to push out the caliper pistons and blew out any crud with my air compressor and then put a little grease on them, blew out the rest of the dust and junk from the calipers, and then reinstalled the pads. Good so far, I'll let you know in a week.

Squeaking occurs when your brake pads are not pulled completley away from the rotors by the calipers. When this happens, the pads tend to float causing a high level vibration; aka "squeak". I just installed a set of aftermarket pads manufactured by Ferodo. I spent a little more money, but it is well worth it. My Disco does not squeak at all under any type of braking conditions.

How about if they squeek while you are lightly applying the brakes? Like you are coming to a light and start stoping but let up halfway on the brake a little to coast a up to the line and then squeak.

exactly my squeal in the rangie, happened right after i put in a brand new set of semi-metallic pads.

Robert, I am still at a loss with the pins - pins in the rovers keep the springy shims from falling out, and nothing on them slides back and forth. And the calipers are of non-floating type.
in any way, my pins were clean, as well as the shims etc. BTW, i find nothing wrong about bringing Scout shit here - a little dose of common sense never hurts :)

In my opinion, it's not the type of material used for the pads. The important thing is the "anti-squeak" part of the pad. A lot of people confuse this material for a grease that actually lubricates the area between the pad and the rotor. This is not how it works. This material is a thick adhesive pad that actually glues itself to the caliper and absorbs vibration. When the pad breaks away from the rotor, a high vibration situation occurs causing the squeal. For those of you who encounter a squeak followed by silence as more brake effort is applied; the pad is re-sealing itself against the caliper. Heavy rain, or heavily wet off-road conditions can cause the pad to break away.

Paul,

all my "other" vehicles except for range rovers had brake pads without anti-squeak part. And every time i used semi-metallic pads (first time by stupidity, all others - 'cause these were the only ones in stock), they squealed like crazy. On the Ford Aerostar, they chipped and broke apart before they wore 1/16" of initial thickness. And yes, I used anti-squeal compound on every one of them.
Last week, put a set of organic pads in the Disco, and no sound at all.

You can use semi-met. pads with good results if you resurface the rotor every time you do it. Unfortunately, the land rover's rotors are pretty thin to begin with, and two resurfacings will take them to the trash bin. My LR dealer insists on replacing the rotors at the sight of a slightest scoring.
