How to Replace Disc Brakes

If your brakes have been squealing and grinding for weeks now, it is time to do a brake job. Not only is it embarrassing but also unsafe to drive a vehicle that needs brakes.

Things You'll Need:

  • Jack Stands
  • Jack
  • New Rotors
  • New Brake Pads
  • Brake Lubricant
  • Disc Brake Quiet
  • C-clamp
  • Basic tools

 

Step 1

Loosen wheel lug nuts and jack vehicle. Loosening the lug nuts before jacking the vehicle makes it easier to take the wheels off. Only jack the vehicle at the frame or any lift points recommended by the manufacturer.

  • Step 2

    Lower vehicle on jack stands and remove wheels.

  • Step 3

    Remove the caliper by unscrewing the two bolts holding it to the caliper bracket.

  • Step 4

    Remove the caliper bracket by unscrewing the two bolts holding it to the steering knuckle.

  • Step 5


    Hammering the rotor

    Remove the rotor. This may be difficult due to the rotor seizing to the steering knuckle due to rust but this can be easily resolved by using a large hammer. Hammer at the base of the rotor (i.e. next to the studs but do not hit the studs). A few good wacks should do and the rotor will be free.

  • Step 6

    Clean the new rotors with brake cleaner to remove the grease coating. The coating is on there to inhibit rust while the rotors sit on the shelves at the auto parts store.

  • Step 7

    Install rotors onto hub.

  • Step 8

    Remove slide pins from caliper bracket and clean the old grease off of them. Re-grease with new brake grease and re-install.

  • Step 9

    Remove the old brake pad holders and replace with the new ones supplied with the brake pads. If your pads did not come with new pad holders sand the rust off of them with 500-600 grit sandpaper. This will allow the brake pads to slide easily and not get stuck on the rotor, which would cause the brakes to wear prematurely.

  • Step 10

    Install the new pads onto the bracket and install the bracket onto the steering knuckle.

  • Step 11

    Open the master cylinder. You are doing this because you are going to compress the caliper. If you didn't open the master cylinder you would cause master cylinder damage.

  • Step 12

    Compress the brake caliper with a c-clamp. This pushes the piston in the caliper allowing you to slide the caliper onto the bracket with ease.

  • Step 13

    Slide the caliper onto the caliper bracket and tighten the bolts.

  • Step 14

    Close the master cylinder.

  • Step 15

    Put the wheels back on and lower the vehicle.

  • Step 16

    Torque the wheels to the specification indicated by the manufacturer. It is typically at least 90 ft. lbs.
