how hard to replace rotors?
 
How difficult is it to replace front brake rotors on a 2000 TJ for someone who has never done that? I recently had pads put on and had em bled so that part is ok. I just need to put new rotors on soon and was wanting advice. I'm somewhat mechanically inclined, just have never changed rotors myself.

I never did one on a jeep but on everyother car is easy. Just take off the tire remove the brake assembly and the rotors just come off.

5 nuts for each wheel, and two bolts for each caliper. Then the rotor should slip off. there might be retaining clips on 2 or 3 of the studs, but they should come off easily.

Also I believe the caliper bolts use an allen wrench instead of a socket.

Thanks, does the brakeline have to be removed and rebled or does it just stay attached to the caliper inntact?

You'll have to let some fluid off of the cylinder in order to get it to let go of the rotor (usually), so you'll probably need to bleed them again. On my '06, the caliper bolts are just standard bolts, not allen, but I'm not sure about an '00. It's super easy, seriously.

*addidition* I don't think there should ever be a need to detach the brake line when performing routine maintenance on your brakes. Again, someone here can keep me honest if I'm wrong, but I've not had too.

Just grab the caliper after its unbolted and rock it back and forth that should loosen it up enough to get it off the rotor. Then slide the rotor off the hub.

Why?

All I do is pull the cap off the master cylinder (to avoid any pressure build up) and then take a big enough c-clamp and use that to push the cylinder back in. I've never had to drain fluid or ever had to bleed the brakes after doing pads and rotors. Keep the old brake pad on the cylinder and put the clamp against that. Screw it nice and slow until it seats all the way down and you'll be good to go. Once you're done, don't forget to put the cap back on the MC.

Yeah you have to make room for the new rotor's thickness, compared to the old one.

And one more thing, after you have it all back together, and before you even move the Jeep, go in and pump the brake pedal a few times.

If not and you forget too, you will have a certain portion of your anatomy clench up as you hit the brakes and the pedal goes to the floor.

I take it that would be your butt hole puckering up!:rofl:

I just changed my rotors last weekend on my 2000. I had to use a puller, heat and a hammer to get it off. They were stuck big time.

y0diggity 03-31-2012 11:09 PM

So apparently you might be able to get the calipers off without any problems. I've not had that experience, but it'll be awesome if you do. Either way, its an easy job. Seriously, just go for it and enjoy the time with your Jeep. :-)

My brakes are pulsating right now a little and I've read that that could mean that my rotors are getting warped and need replacement anyone know anything about this? Sorry for the hijack. Btw i don't have anti lock brakes so that's not the pulsating :D lol

Feel the inside and outside of the rotors. Warping can cause pulsating but so can ringes on the rotor. I replaced mine last week because of this.

Remove the wheel.
Remove the two bolts that hold the caliper - not allen but 13mm wrench. This could differ between years. Swing the caliper and pads out - top first.

Once the caliper is off you can replace the rotors.

Remove the cap from the brake fluid reservoir so that you can push the piston in the caliper back. I usually stick a wrench between the two old pads and hold steady pressure till the piston is flush with the caliper for easy install of the new pads - always install new pads with new rotors.

Warped rotors is a myth..... the rotors don't warp they just get glazed with uneven deposits of brake pad material...
check out this link.... -Warped- Brake Disc and Other Myths
you need to de glaze and re-bed the pads.

Thanks for all the input guys, will definately attempt it...

I had honestly never thought of doing this. :doh:
I've always just opened the zert (sp?) and squeezed the fluid out and then bled the brakes afterwards. I'll be trying it this way the next time I do brakes on a vehicle. Sometimes the simplest solutions are the best, right?

Brakes and rotor are easy once you understand what to do - If you haven't found Stu's site you should check it out. It has an amazing amount of info and pics. Here is a link for the front brakes

Front Brakes Overhaul - 1

Go for it - once you've done it you'll never pay someone again.
