The Volvo S70 was a mid-sized luxury car that was produced from 1998 through 2000. Unlike many automobiles, which use disc brakes on the front brakes and drum brakes on the rear brakes, the S70 uses disc brakes on all four wheels. Maintaining your brakes is an important part of car ownership. Over time, brake pads wear down and need to be replaced. As they wear down, they become less effective at stopping your car, and can even fail, potentially causing injury or worse to you or others.
Park the Volvo on a flat piece of ground and loosen the lug nuts on the front tires.
Jack up the front of the car. Position a jack stand underneath the outer frame on each side and slowly lower the car onto the jack stands.
Remove the front tires.
Disconnect the wires for the anti-lock braking system. The sensor is located on the back of the wheel hub. Locate the electrical wire that leads to that location, and disconnect it by pressing in on the tab and pulling the wire out.
Rotate the bolt on the brake hose a half-turn to loosen it.
Remove the plastic caps from the caliper bolts. Unscrew the caliper bolts and lift the caliper up.
Unscrew the caliper from the hose and drain the rest of the brake fluid into a drain pan.
Take the brake pads off the caliper.
Apply lithium grease to the caliper bolts and slide them into the sleeves.
Screw the brake hose onto the caliper.
Install the brake pads onto the caliper and move the caliper back into position.
Tighten the caliper bolts and place the caps on them.
Install the retaining clip and reconnect the brake hose. Reinstall the ABS wires by plugging the wires back into the sensors.
Repeat this process for the rear brakes, then bleed the brakes.
Remove the brake fluid from the reservoir in the engine compartment with a turkey baster. Fill the reservoir with new brake fluid.
Place a clear tube attached to a bottle over the nipple on the bleeder screw. You can get this at an auto-parts store. Instruct a helper to pump the brake pedal a few times.
Have your assistant press down hard on the brake pedal and hold it. Loosen the bleeder screw on the caliper, then close it right before the brake pedal hits the floor. Repeat this five times, then refill the brake fluid reservoir.
Tell your assistant to pump the brakes 10 more times, then open the bleeder screw again. Keep doing this until there are no more air bubbles in the brake fluid.
Fill the reservoir with brake fluid again, then bleed the other three brakes.
