How-To: Change Front Brake Pads (WK)
 
This is a How-To for the front brake pads for a WK.

****Click here for a How-To for the rear brake pads for a WK.


Tools Needed:


Jack
Jack stands
Blocks
Lug nut wrench
14mm socket (and wrench)
6" C-clamp
Bucket
Gloves

Parts Needed:


Brake pads
Clips
Lubricant

(this should all come packaged together)

**I used Bendix CQ Ceramic Pads (front: D1087, rear: D1080)**


Step 1:
Properly raise and support vehicle, remove wheel/tire assembly.

Step 2:
Use a 14mm socket and wrench to remove the caliper slide pins. These are the two outer bolts on the rear of the caliper.

Step 3:
Pull caliper away from rotor. Notice that the little rubber boots compress (the ones that the caliper pins were screwed in to).

Set caliper assembly aside - I used a bucket - this will make it easier when we have to compress the pistons.

Step 4:
Remove inner and outer brake pads. They simply slide out of the anti-rattle clips.

Once both pads have been removed, remove the anti-rattle clips. The should slide right off with a little pressure.

Clips on

Step 5: Insert new pads into the new clips. Basically reverse the removal steps.

Step 6:
Now, because we have replaced our pads, the pistons are too compressed to fit over the new pads. Using an old pad and a C-clamp, compress both pistons back into the caliper. This will make the caliper able to slide back onto the new pads.

Step 7:
Replace caliper back onto the rotor (pads). Remember that the two rubber boots compress. It may take a little compressing to fit the caliper back on.

Step 8:
Lubricate the caliper slide pins.

Step 9:
Insert slide pin bolts and tighten to 32 ft. lbs.

Step 10:
Replace wheel/tire assembly and lower the vehicle back to the ground; DONE!


This is a super easy, super fast process. It took longer to raise the vehicle and remove the wheel/tire than to actually change the pads, and this was my first time.

The rear pads were slightly more complicated (maybe one extra step), but same deal, super easy and fast.

If you guys have any questions or feedback, I'll be happy to help out as much as I can.

this is JMO.....but I wouldve used a very light sand paper or scotchbrite pad to remove the glazing from the rotors. This will help the new pads to form their own glaze. The glaze is what prevents squeeking etc.(brake noise) You may want to pull the wheels off and do this anyway. This is also why most shops will want to turn or replace the rotors.

Very nice write up by the way!

I am going to be doing my brakes very soon. Is there a lot of added work in replacing the rotors? My rotors are at 85K, so I think they are done...any suggestions toward the roto install and replacement rotors? Hope I am not thread jacking!

Good information. I was going to post if there was any other things I should do or look for while I had the wheels off, but I just wanted to get it done. Next time I'm wrenching on the Jeep I'll do this. Thanks!

From what I've read you just pull the old ones off and slide the new ones one. Just like a wheel. Should be very easy.

hahaha! But seriously, thanks for the help :thumbsup: :)

Well, I started with the rears, and after I got through the first one, it was about 10 minutes on the other rear and about 8 minutes for each front.

Super quick, super easy!

I still had a lot of wear left on my fronts, not so much the rears. I probably should have checked them before getting new pads, but I have put 25,000 miles on the Jeep since I bought it and I had no idea when they were changed before then, so I decided to upgrade anyways.

I'm not too hard on my brakes (i.e. let off the gas when approaching a red light, etc), so these should last me a long time.

I also changed my PCV valve and thermostat (180) today too. I was going to do the spark plugs, but I need a longer 5/8" plug socket; apparently the 3" long one I have now ain't gonna cut it. :(

Yessir. Just make sure the new one goes on EXACTLY like the old one. The little arrows should line up with the tubing. Not sure how it's orientated on the WJ though, so it may be different.
