DIY Brake change '03 & up 2500 4x4's (most likely 3500 as well except drw... slight differences)
Wrench time approx 90~120 minutes.

Do this proceduree at your own risk!!! I am not responsible if you screw up. Consult the manual when in doubt.

This DIY writeup is intended for reference only, you should review the shop manual. It is intended to help those
who are unsure of what they are doing, if your not confident you can do this proceedure, take it to a shop for the
repairs. If you proceed, you do it at your own risk.
While most of us have done brakes before, there are some who have not and might need some help... so here we are
and here we go...

1st off, do not touch the surface of the new pads with your hands at any time, last thing you want is grease from
your hand getting on the pad surface.

Jack up the front end (can do 1 side at a time) and support with jackstand.
Remove wheel


Here is the rotor & caliper assembly


Here is a pic of the Clips holding on the rotor, these will get trashed on removal


Remove the 2 bolts holding the caliper to the caliper bracket using a 13mm socket


Using a screwdriver, pry up on the caliper on the end shown in the pic. the other end slides out of the bracket.
when you begin prying, you will most likely get hung up on the back of the rivet holding the material to the
plate. (circled in the next pic) You will have to compress the piston some to get the caliper off the bracket &
pads. Loosen the brake master cylinder lid so brake fluid has a place to go when you compress the piston. Once
free, support with a wire coat hanger or equivelant. Do not let the caliper hang by the brake lines!!!



Remove the 2 mounting bolts on the caliper bracket using an 18mm socket. (and alot of umph)




Remove the rotor retaining clips and remove the rotor from the hub



If your rotors are not warped or have any groves, you can get away with this step instead of getting the rotors turned, your option.
I have had great sucess sanding down the surfaces on good rotors. I used 150 grit paper. your objective here is
to scuff up the surface so the new pads can bed properly




Once the rotor is preped, slide it on the hub backwards and clean it with BrakLeen (or equiv), then flip it around
and clean the otheside. You can use a lug nut to hold the rotor in place while cleaning & during final assembly
(unless you have new clips, install the clips to hold the rotor in place)



Next make sure you have plenty of room in the master cylinder for fluid. If not you may have to remove some.


Using a brake pad & caliper piston compressing tool, push both of the pistons back into the caliper until they
bottom out.




Next take a rag and clean the vibration clips that are on the caliper. You will be cleaning the area's where the
pads come in contact with the clips.



Pop out the pins that the calipers slide on and put a light coating of grease on them and re-install them. they
are floating inside the rubber boots and will pop out easily. be careful not to tear the boots.




Reinstall the caliper mounting bracket and torque bolts to 130 ft lbs (consult your manual to verify torque specs)
Next put a light coat of grease on the u shaped area on the pads, where they come in contact with the vibration
clips.
This allows the pads to slide easy and will not squeel.


Install the pads and coat the caliper contact points to the pads with a light coat of grease, and on the piston
contact surface.


IF YOU GET GREASE ON THE ROTOR SURFACE OR PADS, CLEAN THEM WITH THE BRAKLEEN BEFORE PROCEEDING.
YOU CANNOT HAVE ANY GREASE ON THE ROTOR FACE OR PAD FACE.

Re-install the caliper onto the bracket and install the caliper and torque bolts to 20 ft lbs (consult your manual
to verify torque specs)


remove your lug nut and re-install the wheel. Torque wheel lug nuts to spec (consult your manual for proper
torque spec, I used 100 ft lbs)


Use the same procedure for the other side, once completed check the fluid level in the master cylinder and top off
as needed. make sure you close the lid before moving the truck.


Now for the fun stuff... jump in the cab and fire it up, apply the brakes a few times to push the pistons out to
the pads. 1st couple of times the pedal will go to the floor as the pistons move out to the pads. Once you have
a reasonably firm pedal, it's time to seat or bed the pads.

Beding the Pads & Rotors (taken in part from another publication off the web)

This procedure is best done in the country or on an empty road where you can not affect traffic.

From about 60 mph, gently apply the brakes to put some heat into the pads & rotors. This will bring them up to
operating temperature and will prevent you from thermally shocking the pads & rotors in the next steps.

Once the brakes are up to operating temperature, speed up to about 60 mph and stomp on the brakes hard and reduce
your speed to about 10~15 mph. Apply the brakes hard enough so that your not locking the wheels and the ABS is
not activating.

Once you reach 10~15 mph, accelerate back up to 60 and repeat 5~8 times until you feel the brakes fading. Once
they are fading your ready to cool the brakes down. Your brakes will most likely stink, this is normal.

Accelerate back up to 55~60 and drive for approx 10~15 minutes to allow the brakes to cool down. Try not to use
them as much as possible and avoid getting stuck in traffic. If you get stuck in traffic and come to a stop
before the brakes have cooled, "you will imprint pad material onto the hot rotors which can lead to vibration,
uneven braking and could even ruin the rotors"

After the 1st breakin cycle, you may need to let the brakes cool 100% and repeat the procedure to get the best
performance out of your brakes. (it's up to you).
