Wheel Cylinders: Inspection

With brake drums removed, inspect the wheel cylinder boots for evidence of a brake fluid leak. Visually check the boots for cuts, tears or heat cracks. If any of these conditions exist, the wheel cylinders should be completely cleaned, inspected and new parts installed or the wheel cylinder should be replaced. If a wheel cylinder is leaking and the brake lining material is saturated with brake fluid, the brake shoes must be replaced.
