Both wheels should be worked with simultaneously and both disc brake pads replaced one at a time with the other assembled brake serving as a guide in case of necessity. Asbestos dust may be hazardous to health so when handling the brake system be careful of it. To start, unscrew a top of the brake fluid reservoir and siphon, approximately, two ounces of brake fluid into a container to be discarded. Unscrew the bolts of the front wheel, lift the front part of the vehicle, and hold it toughly on jackstands and take out the front wheels. Then drop the two caliper bolts and lift the caliper out of the disc. Take a screwdriver and loosen the clips and remove the outer pad, and then pull off the inner pad of the caliper. Check caliper boot; peel back edge checking that there is no leakage of fluids. Insert the caliper back into the piston until it bottoms out with a C-clamp and insert the inner pad and snap it into the piston. Then insert the outer pad into position and attach it to the caliper before turning the caliper back to position. Connect the bolts and tighten them to the desired torque and then bleed the brakes and finally fix the wheels after which the vehicle should be lowered.
