Looks like a piece of cake eh? Nah, really, looks like tough stuff to lots of people, but it's VERY easy.

It actually is, and if you follow these instructions, replacing the pads/rotors should take 10-15 minutes for each side. Yes, you can do your rear brakes in 1/2 an hour!! See that handbrake cable? You shall NOT be messing with it or taking up hours trying to put it back with it's Godforsaken spring, plus it is in the way of the bottom 15mm bolt. If you attempt to take it off, it will not come off. Why? Because the cable is in the way. We shall not be going that nutty route, we shall do it the east and fast way. Ready?

For regular street driving, I recommend Motorcraft pads however, for aggressive street driving with absolutely ZERO brake fade after 90+ speeds, I recommend Hawk pads. Part # HB111F.610 for the fronts, and HB183F.585 for the rears and are in the same price range as the Motorcraft pads.


1. Jack said car up.
2. Take respective wheel off

3. Take the two 13mm bolts off. They are located next to the accordion boots that house the caliper sliders. In this pic below, I have the 13mm wrench on the bolt, and I'm using a larger deep socket over the smaller wrench for leverage and to prevent discomfort from my palm.

4. Then it's onto the 2nd 13mm bolt..(Steps # 3 and #4 should take 1-2 minutes at the most).

*Note* For 99-04 COBRA IRS setup, at this point, you have to first remove the little screw that holds the handbrake cable to the rear control arm. This is located where the rear spring sits in it's perch. There is a little bracket that holds the handbrake cable to the arm...as shown in this photo below:

5. Caliper comes off very easily...just lifts up...and also moves that dreaded handbrake cable out of the way of the two 15mm bolts that you'll be heading for next. (Notice that the pads are still in place?..pretty cool huh?)

6. At this point, you can use a rear caliper screw-in tool ($5-10 at any local auto parts store), or just rent a much better kit such as this or buy one for yourself. www.Harborfreight.com sells the kit for $29-39.00

6. (a) Screw the piston in as shown:

Step # 6 takes about 2 minutes of grunting...still very easy!!

NOTE: Align the PISTON INDENTATIONS in an UP/DOWN orientation so that they line up with the little bumps on the brake pad.

7. Now, if you're replacing the rotors, grab a breaker bar, a 15mm socket and a nice large socket wrench, and take those 2 (totally exposed/unobstructed) 15mm bolts off. *Never use a torque wrench for this. Wrench shown was for illustration purpose only*

Another angle: (see? no handbrake cable in the way) Yay!

Step # 7 is necessary IF you're going to take the rotors off and either replace them with new ones, or going to take them down to your local parts store to have them resurfaced with a lathe. (takes a very fine layer off and makes them nice and flat surfaced).

8. When that process is complete, replace the bracket and resinstall the two 15mm bolts (Use some thread locker/locktite on the bolt's threads first). Then place the new pads as shown with the anti-rattle clips at both ends.

9. Slide caliper back onto the bracket are remembering to align the piston indentations with the small bumps in the middle of the inner brake pad. You can then install the two 13mm bolts back onto the sliders with the accordion boots.


(ALSO NOTE: This would be an EXCELLENT time to slide those boots off to expose the shiny sliders inside. Grease them with some high temp grease and they should be good until the next brake pad change. This prevents a very common problem of rear caliper SEIZING which is normally due to exposed sliders that have gone dry and caused the heat from the calipers to seize the little slider piston into the caliper...and prevents use of rear brakes and can be very dangerous.)

Thanks

Can you take off the rotors without messing with the parking brake? Looks like it.

I was actually worried about doing the rear brakes because I kept hearing that you needed to mess with the parking brake spring.

I need a how to on changing studs. I have one that is in really bad shape. Can you get the rotor off without messing with the parking brake and how do you get the studs in and out? is that something left to a mechanic who has the proper tools?

When you're at step 5, the caliper with spring are out of the way. No messing with the spring whatsoever.

When you get to step 7, the caliper bracket is out and the rotor slides off.

With the rotor out, you can see the studs. I do not recommend hammering them out since that will damage your bearings and locker inside your axle.

This is a method that's known to work:

Get a vice grip, grab a socket that is larger than the back of the stud, place the vice grip as shown with the head of the stud covered by the socket, and then screw the vice. The open socket will allow the stud to go inside it from the back while it slides out of the axle shaft.

I found this pic on the web

..and here is how to reinstall the new stud. See the socket is now at the front.

great

awesome.. Thats great. Thanks..

Right ups like these are really helpful. Its too bad that people dont put these things written this simply into a book. The haynes book is very unclear and written for different models..

I would love to do all my work myself. I have thought about asking the mechanic i hire if I could pay him more by the hour to actually show me what to do. Im also considering taking some classes at Lincoln Tech.

I NEVER would have tried to replace my alternator if it was for the right up in here. I didnt even know how to change my oil when I bought my first mustang. Now im changing my own fuel filters...did brakes on my truck with new rotors, alternator, plugs, pulleys and more. Its really great. Thanks again.

When screwing the piston back into the caliper BE SURE to align the two little V-cuts in the face of the piston straight up and down to the caliper. The two little pin tits on the back side of the pad need to fit into these recesses. If you don't pay attention to this it will cause the brakes to drag and wear out prematurely.

FWIW,

I just did this and checked the forum to see what tool you guys were using to compress the piston...

I noticed people are under the impression those bolts are 13mm... they're 12...

Also a helpful step to note would be make sure the e-brake is down otherwise you won't have enough slack to get to the pads on the drivers side...

Stupid question... do they need to be bled after this? :shrug:

I don’t think they have to. As long as you don’t disconnect the break line from the caliper you shouldnt..

I really wish someone would have told me you had to ‘screw in’ the rear piston … I felt like a fool after I found this out..

Depending on the year and depending on the "slider pin" set-up in your car there were two different bolts and two different styles of slider pins used. One was fine thread and one was coarse thread. Your bolt heads will vary accordingly. I've seen them in 12mm, 13mm, 14mm and 15mm wrench sizes which includes aftermarket replacement parts.

It's always a good idea to flush the old fluid out of your system when working on your brakes. Bleed the brakes when you're done. This will keep fresh fluid in the calipers and flush the contaminants out. By keeping the contaminants out you will prolong the life of your piston and piston seal.

FWIW

I just did an EBC pad/rotor swap and painted the calipers this weekend. Granted that this was the first brake job I have done on the car, but I didn't think the rears were difficult at all.

Removed the small (12mm?) bolt that holds the ebrake cable to the spring perch.
Removed the c clip that holds the ebrakes cable to the caliper.
Pulled the ebrake cable out of the caliper and lower a arm? mounting holes
Proceeded to clean / paint / install.
Didn't have any trouble putting the ebrake cable back through the mounting holes, replacing the c clip or reattaching the spring perch bolt.
It was a piece of cake.
