Volvo S80 Rear Brake Pad & Rotor Change

 vegasjetskier » Here’s how to change the rear brake pads and/or rotor on your 2001 S80 T6. This might apply to other models or years of the P2 cars. Sorry if some of the pics are out of focus – it was tough to hold on to everything with one hand and work the camera with the other. I had to replace the disc and pads on one wheel of my car because one of the factory pads (yes, Volvo brand) was machined improperly and got stuck in the caliper. It kept the pad in contact with the disc and wore a bevel on one side of the rotor. This time I decided to use Akebono ceramic pads and a Centric rotor (the rotor that got ruined was a Brembo). Sorry I couldn’t include all the pics – there’s a limit of 24. Read through the whole post before starting any work.

Tools and supplies you will need

  • Floor jack (or use the jack from the trunk)
  • 10mm socket or end wrench
  • 13mm socket
  • Ratchet wrench
  • 7mm Allen bit
  • Flat Screwdriver
  • Disc Brake Cleaner
  • Rags or paper towels
  • Disc Brake Grease

  • Wire brush
  • 1 Gallon Paint Can
  • Hammer
  • Torque wrench

S80 T6 2001 Rear Brake Pad & Rotor Change


Procedure

First, chock the wheels on the opposite side of the car. Loosen the lug bolts on the wheel you will be working on. Make sure the transmission is in Park. Jack up the car and remove the lug bolts and the wheel. Release the parking brake.

Use the screwdriver to pry one side of the anti-vibration spring loose:

New brakes and rotors - Volvo S80Then pry at the bottom. You may need to alternate between the top and bottom a few times to get the piston back in.

Now remove the plastic caps from the two caliper pins at the top and bottom of the caliper:
New brakes and rotors - Volvo S80Now remove the wheel speed sensor cable from the two clips:
New brakes and rotors - Volvo S80Use the 7mm Allen bit to loosen the top caliper pin:
New brakes and rotors - Volvo S80Use the Allen bit to loosen the bottom pin:
New brakes and rotors - Volvo S80Now set a paint can or other suitable stand near the swingarm. Slide the caliper off the bracket and outside pad:
New brakes and rotors - Volvo S80And set it on the paint can (this is to prevent straining the brake line). Remove the pins from the caliper:
New brakes and rotors - Volvo S80Now push down on the inside pad to remove it from the piston:
New brakes and rotors - Volvo S80Remove the outside pad from the bracket:

Now use the 13mm socket to remove the bracket bolts. First the top bolt:

New brakes and rotors - Volvo S80And remove the bracket:
New brakes and rotors - Volvo S80Use the 10mm socket or end wrench to remove the disc stud:
New brakes and rotors - Volvo S80Then pull the disc off the hub. If the disc is badly rusted to the hub, you may need to use a hammer to break it loose. A couple thumps should do it:
New brakes and rotors - Volvo S80IMPORTANT: Clean the new disc with disc brake cleaner: it probably has an anti-corrosion coating on it that needs to be removed before the disc is used.

Wire brush the hub to remove any rust or scale, then place the new disc on the hub and secure it with the stud. I couldn’t find a torque for the stud, so I just tightened to what seemed like a sufficient amount. Don’t overtighten as you might strip it.
New brakes and rotors - Volvo S80Use a screwdriver or other suitable tool to scrape down the machined flat surfaces on the caliper bracket. This is where the pads slide as they wear down. Clean the surfaces with disc brake cleaner and a cloth or paper towels, then apply grease made for disc brakes.
New brakes and rotors - Volvo S80Place the bracket back into position and install the bolts. Tighten the bolts to 44 ft-lbs of torque.

Scrape down the “fingers” on the brake caliper, clean them with disc brake cleaner and apply grease.
New brakes and rotors - Volvo S80Snap the new inside pad into the piston:
New brakes and rotors - Volvo S80Set the outside pad in place on the caliper and apply grease to the area where the caliper fingers will touch:
New brakes and rotors - Volvo S80Clean and grease the caliper pins and insert them into the caliper. Slide the caliper over the bracket and outside pad and screw the pins into the caliper bracket. Tighten the caliper pins to 22 ft-lbs of torque. Push the plastic caps back into the caliper pin holes. Push the wheel speed sensor cable back into its clips.
New brakes and rotors - Volvo S80Place the spring onto the caliper as shown. Tap the ears into the holes on the side of the caliper:
New brakes and rotors - Volvo S80Now pry the spring over the top and bottom caliper ears and into position:
New brakes and rotors - Volvo S80This is what it should look like when you’re done:
New brakes and rotors - Volvo S80Reinstall the wheel and lower the car to the ground. Tighten the lug bolts to 103 ft-lbs. Pump the brakes a few times to bring the pads into contact with the disc. Set the parking brake and remove the wheel chocks. Repeat the procedure for the other side of the car.

Congratulations, you’re done!

Take it easy on the brakes for the first few hundred miles to give the pads a chance to seat into the discs.
