Park the car on a level, hard surface, such as a garage floor or concrete driveway, Engage the parking brake.
Jack the front of the car and place the axle stands firmly in position for safety support.
Loosen the front wheels.
Remove the wheels, unlock the steering and turn the wheel full lock to one side, so the brake caliper is exposed and easily reached.
Open the bonnet and locate the brake master cylinder, Remove the filler cap and place a clean cloth over the filler hole, this is to absorb the brake fluid that will be expunged when the brake caliper’s piston is forced back and prevent the brake fluid from leaking all over the vehicle.
NB, brake fluid will eat away at the paintwork of the car, so be extra careful not to spill any.
Place a piece of old cardboard below your work area to catch all loose debris.
Take a screwdriver or any appropriate lever and pry the disc pad away from the disc and toward the caliper’s piston. The caliper’s piston will move back gradually, continue applying pressure, until the piston is all the way back. As you do this the brake fluid level will rise in the reservoir, hence the clean rag placed there.
Loosen the brake caliper bolts,
Remove the caliper bolts.
Remove the caliper and tie it with cable ties, or a bungee cord out of the way, ensure that you do not damage the flexible brake hose attached to the caliper.
Check the caliper sliding pins and ensure it moves freely.
Remove the old disc pads
Brush away all loose brake dust and debris with an old paintbrush. Check the condition of the brake discs, replace if necessary.
Fit the new brake pads with the abrasive lining facing the brake discs,
Re Fit the brake caliper
Fit and tighten the caliper bolts by hand ensuring not to cross thread.
Tighten sufficiently with the appropriate size spanner. Hand tight with a bite will be tight enough.
Pump the brakes pedal repeatedly until the brake pedal is firm. You are now pumping the brake fluid back into the brake lines, that was pushed back when the caliper piston was forced back when removing the old brake pads.
Repeat the above procedure for the opposite side.
When completed, remove the rag covering the master cylinder filler hole, ensure the brake fluid level is at the max mark, if not top it up. Fit the filler cap securely.
Fit the wheels. lower the car to the ground and tighten the wheels appropriately with a wheel brace.
Test the brake pedal, ensuring that it is firm before you drive off.
Congratulations you have just completed the fitting of new front disc brake pads.
