How Does Your Brake System Work?
- Master cylinder
The master cylinder is the heart of your brake system. It pumps brake fluid to the wheel cylinder and/or calipers when you push down on the brake pedal. The fluid reservoir level of the brake system can and should be visually inspected from time to time. It is recommended that brake fluid be replaced approximately every 12,000 miles.
- Calipers and wheel cylinders
The function of the calipers (or disc brakes) and wheel cylinders (or drum brakes) is to convert the energy of the pressurized brake fluid into pressure to operate the brakes. A periodic inspection for leaks or corrosion around the rubber seals should be carried out to maintain good working order.
- ABS (anti-lock braking system) sensors and controller
Your ABS system is electronically controlled. This system detects problems—some of which can be self-corrected, while others will shut down the ABS system—causing the ABS light on the dash to be illuminated. Some problems are recorded in the vehicle’s computer for the technician's reference when servicing the braking system.
- Brake pads and shoes
An inspection will determine if you need to replace your brake pads and shoes. This procedure is referred to as a "brake job" and should be carried out frequently to insure maximum performance.
- Parking brake
Most modern rear brakes rely on proper parking brake usage to assist in keeping the rear brakes adjusted. If you don't use your parking brake regularly, ask your technician to lubricate the cables and check the adjustment, as infrequent use could cause a low brake pedal or corrosion causing the brakes to drag.
