I have a '96 Disco with nothing special to add extra weight. When coming to a complete stop, just before I do so, I feel a grinding coming through the brakes. My brakes have always had a very audible (and quite annoying) screech, but this is different. It only happens as I near a stopping point, never when using the brakes to slow.

You better have the brakes checked. Sounds like you are metal-to-metal. You do not have any brake pads left on the shoe. By this time you have damaged the rotor(s).

yep, you are probably out of pad. the disco does not have a warning squeeler to let you know you are getting low. also look to see if you have a lot of brake dust on your rim. if you do get it off of there asap, it is metal shavings and will stick and rust onto your alloy rims ruining the finish (if thats your thing). just slap new pads on and dont worry about new rotors, you'll be fine.

Better yank wheels off and check pads (or where pads used to be)...do it yourself - it's a very simple procedure involving pliers and an hour of your time. You may even get away with fitting new pads on scored rotors...or you may have to slap on new rotors, too.

email me if you want help with the pad replacement - I might even have pictures.

Bill,
To swap the pads, my manual calls for the piston-vise from LR and I am sure it costs some rediculous amount. Did you purchase something in leiu of the LR tool? If so, where did you get it?
Thanks,
Bruce

I had the same sound and just needed pads. Be careful, because I took my disco to an independent rover shop here in Miami who said I needed a full brake job for $900. I sent him to hell and did the brakes myself for under $150 (used genuine rover pads). That was before I found this board. Next time, I know better than to spend that much for pads.

I guess any autoshop will have the vice you need, cos any car needs 'em.
Basically what happens is this: As the pads get worn they get thinner. This reduces the level in brake fluid reservoir. Whan replacing the worn pads, you will have to push the pistons back to allow space between piston and rotor/disc for new pads - so you'll have to open reservoir cap to allow the level to rise again.
Open reservoir cap, and you force the pistons into caliper. THey are supposed to move freely !!!
The vice allows you to push in both pistons at a time, but any clamp (for instance the one you use for gluing pieces of wood) will do - you just take one piston at the time. NO FORCE. CHK my site on this. Use the makedo clamps with care, and do not push directly on piston, use the old pad (only when you use makedo tools).
As any disc-braked vehicle will need same procedure, any shop will prolly have what you need. Take a look on it, and you'll see what I mean.
Good luck!
Frode

Somebody told me once that some Discos and some Rangies have electronic wear sensors in the brake calipers. Does anybody know if this is true? I haven't had to do a brake job on my truck yet (but it's getting close) and was wondering if I'm gonna have a light come on my dash to tell me my brakes are worn-out. I keep a check on my pads anyway, but this sensor thing sure would be convenient. Thanks for any info!

Jon

I have a Range Rover and my pad wear indicators did NOT work. I installed the new pads myself, easy as can be. I can also verify that they have pad wear electronics in the pad, but for some reason it did not trigger the light, and my rotors were well scored by the time I realized they were so bad off. So just be careful to check them out occasionally.

Discos do not have the pad wear sensors. You can just compress the pistons with the old pad in place with a screwdriver - works fine. Some say you shouldn't force old fluid back through the ABS system, and they're probably right, but have never had any problems on my end. Also - you can get very good pads w/out spending the LR genuine price. (www.brakeco.com)

Jon !
Yes, there are wear sensors on your Disco. On right hand side, think it's outside pads. Having said that, you will know that it is the OUTER pads on RIGHT side which will warn you of worn pads - any other worn down will not...
Pads do wear unevenly, and on my Disco the wired one is not the one worn most, so I just cut the crap and cut the wire: I have to look after it on my own - which really is what you have to do anyway.

I find that a large 'C' clamp works great for a brake piston compressor. No need for anything fancy...just get a big enough C clamp for a few bucks. Gotta be a good sized clamp, no little sissy clamps will do. Use a old brake pad to cover the tops of the pistons.

Frode,

When you say right side are you talking when sitting in the rover or looking at the front of the rover.
Also do you have pictures of the wires you cut?

Rob!
Right side when sitting in vehicle (i.e. starboard...)
You can't really miss it, because there are two wires sticking out from one of the pads, attached to this you'll find a round plug, going into a round socket. If you have removed all pads from calipers and none of them are still connected to the vehicle via a wire/connector, your vehicle has one of the aftermarket pad without the elec-trics. You should then see a loose connector hanging somewhere.
As said earlier: You won't need it because you can't trust it because the uneven wear...

I've still never seen an NAS Disco with the brake pad wear sensors - only RR's. Maybe pre-95?
