When you brake, your pedal force gets extended to the vehicle, which in turn, causes it to stop. The brake master cylinder is the one responsible for this mechanism. It converts the force you apply on the brake pedal into hydraulic pressure in a dual braking system. When your master cylinder becomes worn, it is best to replace it immediately.
Flexibility at your hands
In choosing your new master cylinder, it is essential to know what options you have in the market. Master cylinders are usually available individually or sold as a kit.
- Individual brake master cylinder ? If the brake master cylinder is the only part of your vehicle's brake system that's damaged, then you might want to get an individually sold master cylinder. However, going for this option is a bit risky. During the installation, you might discover other parts to be worn out as well. This only means that you'll have to spend another visit to the auto parts store to get another part, which could have come with the brake master cylinder sold as a kit.
- Brake master cylinder kit ? As a kit, a brake master cylinder comes with a reservoir and a bleeder kit. If you seek assurance and want to save time and effort in repairing your brake system, then the master cylinder kit is what you're looking for.
Convenience through your preferred cylinder
Different types of brake master cylinders suit different vehicle needs as well. Below is a brief list of the common master cylinder types.
- Single cylinder ? most basic type. It starts with the plunger pushing fluid into the slave cylinders. The spring then returns the plunger to its original position. With negative pressure, fluid gets pulled from the reservoir to the cylinder.
- Ported tandem cylinder ? has two pistons in one cylinder. It works using the combined effort of the primary and secondary pistons. The primary piston presses on a spring, which is attached to the secondary piston. When the spring gets fully compressed, the secondary piston begins pushing fluid to its own dedicated system. Pressure on both sides is evened out through a reservoir inlet. Releasing the brake pedal allows the pistons to return to their original position.
- Portless master cylinder ? This type gives quicker brake release than the standard master cylinder designs. Portless master cylinders use a valve assembly located in the pistons, which opens to balance the [ressure when the brake is released. This enables the master cylinder to work despite the absence of a compensating port. Its key feature is its anti-locking braking systems (ABS), which adjust braking force using rapid pressure modulations.
