How do you read a brake diagram?

In order to read a brake diagram, become familiar with each component, routing lines and fittings. Then, use the diagram as a point of reference with the repair steps that accompany it. The brake diagram itself is used to help a mechanic visualize where each component goes while replacing parts easily.

Use these following instructions to read a brake diagram properly.

1. Become familiar with the components

A brake diagram has several different components on it. Study and become familiar with each one. Most vehicles, for example, utilize a disc brake system. These brakes have a rotor which spins on the hub, caliper and brake pads. The caliper is a special component that uses hydraulic fluid to compress the pads onto the rotor. The diagram will have each of the parts drawn in their correct mounting locations.

2. Know the brake lines

Hydraulic fluid travels from the master cylinder to the caliper. The brake line will usually be mounted the strut tower. Be sure to remember its location.

3. Do not lose the fittings

The fittings are found on the brake caliper, and are required when bleeding the system. Remember where each fitting is, what it looks like and its size.

4. Cross reference it with the brake system

Once the diagram has been understood, use it as a guide to replace any of the brake components on the vehicle.
