I bought Land Rover Discovery II Brake Parts: Brake Rebuild Kit - Front & Rear from BA. The calipers and brake pads front and back. Any advise for tomorrow's install. Any odd tools i might need to run out to northern tool get. Do I need to bleed the brakes. They look ok, but they are slightly out of spec. so we are taking a trip to the smokies so I might as well change them out.

 

If it takes you more than a hour you shouldn't;t be doing the work.

Super easy, basic tools, done.

The hardest part will be removing the retaining screw on the old rotors, throw it away and do not use any retaining screw on them, all that screw does is hold the rotors on as the truck moves down the assembly line on a conveyor.
The wheels actually hold the rotors on.

 

super easy job. i just did my fronts. it couldn't hurt to bleed the brakes.
the only tool i didn't have and had to go get, was either a 18mm, or 19mm, can't recall, 12 point wrench. the bolts that remove the calipers are 12 point vs. the typical 6 point. gave me a reason to go buy a nice set of 12 point combination wrenches.

You'll need something to press the caliper pistons back into the calipers. I've used a fairly large C-clamp and a small block of wood, but the proper tool is not expensive. You might also need an EZ-out to remove the caliper screws. I did. As Spike said you don't need to replace them. A large Philips head screwdriver may get them out but they're actually #4 Posi Drive heads, IIRC.

 

Did all 4 wheels and it too about 45 minutes for all 4 wheels. For the retaining screw, i used a punch impact tool. Worked perfectly. For compressing the piston. I used a c-clamp and the old pad to compress. Important tip, when compressing, first remove the cap off the master cylinder, then compress slowly.

 

like every one has said basic job, take your time and it will be fine, hardest part is the grub screw on the rotor that every body has said about. Make sure you have some break clean to clean off the protective coating on the new rotors and then to give them a clean once you have fitted every thing so no greasy/oil spots are on the rotors. I also use cooper grease on the back of the bads and the slide groves on the claipers to stop break squeel. Bed the breaks in carefully. Let us know how it went

 

And yes, you should always bleed your brakes, it will take 2 quarts of DOT 4 to do properly.
