Repair of the wheel brake cylinder

If the wheel cylinder is not required to replace, it can be dismantled in the established state. Previously, remove the brake pads. Wheel brake cylinder should be replaced at the latest when the brake fluid penetrates the cuff. When replacing brake pads must always be removed from the cylinder anthers and look into the cylinder. If the anthers of the wet or the entire wheel cylinder covered with brake fluid, replace the cylinder. Also replacement is required if the pistons in the cylinder slide with difficulty, are grooves or rust. In one of these cases, the wheel is braked or not, or permanently inhibited.

Cover both the piston and the cylinder surface with special grease for brake cylinders, for example, the company ATE. Do not use the old grease, or brake fluid is contaminated. Insert into the left wheel cylinder piston. Insert left and right spring piston. Wear anthers. Install the brake pads and brake drum. Bleed brake system.
