Procedure

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.

Jack The Car Up Safely

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.

Loosen Brake Caliper

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.

Cover Master Cylinder

Place a piece of old cardboard below your work area to catch all loose debris.

Push back the Caliper Pistons

Take a screwdriver or any appropriate lever and pry the disc pad away from the disc and toward the caliper’s piston. The caliper 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.
