About Brake System Bleeding

The disc brake hydraulic system can be bled manually or with pressure bleeding equipment. On vehicles with disc brakes the brake pedal will require more pumping and frequent checking of fluid level in master cylinder during bleeding operation.

Never use brake fluid that has been drained from hydraulic system when bleeding the brakes. Be sure the disc brake pistons are returned to their normal positions and that the pad assemblies are properly seated. Before driving the vehicle, check brake operation to be sure that a firm pedal has been obtained.
