  Q: How to replace a front Brake Pad Set on Volvo S70?

  A:

  Loosen the bolts at the front of the wheel, and chock the rear wheels, and then jack up the front of the car and support it on axle stands. Remove the front roadwheels, taking note of how the locating peg fits into the back of the wheel. Using a screwdriver, carefully remove the brake pad retaining spring clip, being careful not to deform it. Remove the protective caps from the two caliper guide pins, and then unscrew both pins with a 7mm hexagonal socket. Withdraw the caliper off the brake pads and caliper bracket and take care not to stretch the brake hose. Remove the inboard pad with spring clip retainer from the caliper piston, and the outboard brake pad from the caliper bracket, hanging the caliper in the air with string or wire attached to some convenient suspension part, without pressing the brake pedal while the caliper is removed. Measure the thickness of the pad friction linings, if any of the pad linings are worn down to the specified minimum, renew all four front pads and do not interchange pads to even out wear. Clean caliper and bracket with a damp rag or old paintbrush, checking caliper piston and dust boot for signs of fluid leakage, check guide pin rubber bushes, repair or replace. Remove any scale or rust from the outside rim of the Brake Disc using a wire brush or file, checking the visible surface of the brake disc for deep scoring, cracks or grooves, and make a more thorough inspection if brake judder or snatch has been a problem. If new pads are to be fitted, press the caliper piston back into its bore using a pair of pliers, being careful not to damage the dust boot, and remove some fluid from the master cylinder reservoir to avoid overflowing as the piston is pressed back. Position the outboard pad in the caliper bracket with the friction surface towards the disc and engage the spring clip retainer of the inboard pad with the caliper piston and push the pad into full contact with the piston, before placing the caliper over the disc and on to the caliper bracket. Lubricate the guide pins with silicone grease, insert the guide pins into the caliper and tighten both to the specified torque, refit the guide pins protective caps and brake pad retaining spring clip. Press the brake pedal several times to force the pads to the disc, repeat the operations on the other front brake, refit the roadwheels, lower the car and tighten the wheel bolts in a diagonal order to the specified torque. Check the brake fluid level and top-up if necessary and, if new pads have been fitted, avoid hard braking during the first few hundred miles to allow the linings to bed-in.

  Q: How to replace a rear Brake Pad Set on Volvo S70?

  A:

  Loosen bolts on the rear wheel and chock the front wheels, then jack up the rear end of the car and place the car on axle stands. Remove the rear roadwheels, keeping track of how the locating peg fits into the back of the wheel. Drive the two retaining pins out of the caliper with a hammer and punch and recover the anti-rattle spring and take note of its fitting. Get a new spring for reassembly. Use pliers to press each pad away from the disc, without using leverage between the pads and the disc. Pull the pads out of the caliper along with the anti-squeal shims, if fitted, identifying their position for reuse, and do not press the brake pedal with the pads removed. Measure the thickness of the pad friction linings, if any pad lining has worn to the specified minimum thickness, then all four rear pads will need to be renewed. (Do not inter-change pads to even out wear.) Clean the caliper using a damp rag or old paintbrush, check the caliper pistons and dust boots for signs of fluid leakage and repair or renew them as needed. Inspect the visible surface of the Brake Disc for deep scoring, cracks or grooves, and if brake judder or snatch has been a problem, do a more thorough inspection, removing the caliper if necessary in order to access the inboard face of the disc. If new pads are to be fitted, push the caliper pistons back into their bores using pliers removing some of the fluid from the master cylinder reservoir to prevent overflowing. Fit the pads and shimming into the jaws of the caliper with the friction surfaces towards the disc. Insert the upper pad retaining pin with the anti-rattle spring, tapping the retaining pin all home, and fit the lower pad retaining pin in the same manner, making sure that the pin goes over the tongue of the spring. Pump the brake pedal several times to seat the new pads to the discs and repeat the operations with the other rear brake. Refit the roadwheels, lower the car and tighten the wheel bolts diagonally, to the specified torque. Check the brake fluid level and top up if needed and if new pads have been fitted, avoid hard braking for the first few hundred miles to allow the linings to bed-in.
