| Brake Wheel Cylinder |
Brake bleeding must be performed whenever the brake pedal felt 'spongy' or any brake components are replaced, for example, brake shoes, brake pads, brake calliper pistons, brake wheel cylinders or every 50,000 km or 5 years or more. Vehicles that are 5 years or more will have brake fluid heavily contaminated and the water absorbed in the brake fluid will corrode the brake wheel cylinders, the brake piston chambers etc.. Brake bleeding at the rear wheels normally will show a highly contaminated brown fluid oozing out of the brake nipple.
