Wheel cylinders are vital parts to your car's brake system. Its job is to exert the right amount of brake fluid into the system depending on how hard you pressed the brake pedal. The wheel cylinder is composed of a steel cylinder containing a piston, and covered by two rubber caps on both ends. The peripheral parts of the wheel cylinder are usually the ones that corrode first which makes it more convenient to rebuild the cylinder rather than to replace it entirely. Because of this, the wheel cylinder repair kit was created-to make wheel cylinder rebuilding much easier. Some manufacturers provide different sets of wheel cylinder repair kits-to know what parts are essential or not, here's a short guide to help you choose the right wheel cylinder repair kit.
Rubber caps are important parts of the entire kit as they are usually the ones that get broken first. Make sure to buy repair kits that include the best quality of rubber caps. Rubber caps should be leak-resistant, and made from durable rubber material such as polymer-based composites among other variations. Aside from keeping the piston securely placed inside the cylinder, the rubber caps also prevent brake fluid leaks.
Wheel cylinder-honing tool
The wheel cylinder-honing tool is used to remove mild corrosion from within the metal cylinder. This is an important tool in cleaning the wheel cylinder during the rebuilding procedure, so make sure to buy repair kits that include high quality honing tools. The best cylinder-honing tools are usually made from stainless steel springs with rubber holders to control the rotational movement it needs to do once inserted onto the cylinder.
Brake cylinder pistons
The brake cylinder piston is the most important part of the wheel cylinder. It plays a vital role in pushing the proper amount of brake fluid to gradually slow down the vehicle to full stop. Without stainless steel pistons, the wheel cylinders will easily corrode, and you might have to rebuild the wheel cylinders more often.
