Before fixing or repairing the Wheel Cylinder, you should take out the bleeder valve, boots, pistons, seals and spring assembly. Watch out for scratches and rust develop inside the cylinder bore and inspect the spring by looking for signs of heat damage; if something is wrong, get a new spring. If any scoring is still present inside the cylinder, you should replace the Wheel Cylinder. Later, use clean brake fluid to clean the inside of the cylinder. To install, grease the pistons, seals and inside the cylinder with clean brake fluid and after that, fix the spring, seals, pistons and boots in their place. The last step is to add the bleeder valve and tighten it to the setting of 13 nm (110 inch lbs.).
