How to Install Hydraulics on a Car

So you've determined you need to upgrade your brake hydraulics to compensate for the new braking system. Installing car hydraulics might seem difficult, but you can do it with a some tools and a little knowledge. Here's how to install car hydraulics so you're sure of your new brake's stopping capabilities.

Difficulty: Moderately Challenging

Instructions

1. Put the car up on a lift because you don't want to install hydraulics on a car without one. If you don't have one, borrow a garage lift to make the job much easier.

2. Remove the pedal assembly, the booster, then the master cylinder. In most cases, there is a clip that holds the pedal assembly to the booster. Use your wrenches and a good Clymer or Hayes manual as reference for your make, model and year of car to do this.

3. Replace the brake lines with new and remove the calipers that are no longer attached to the old discs. Remove the distribution block after you have disconnected the line that feeds the rear brakes.

4. Install a new booster, master cylinder and distribution box. Follow the manufacturer's directions and make sure the part is compatible with your make, model and year of car. Clip the new booster to the pedal assembly using the same clip. Install a "T" fitting to evenly distribute the fluid to both front brakes.

5. Hook the lines up to the calipers, the "T," the master cylinder, the distribution box and the rear breaks. Check all connections and bleed the brakes after installation. Have a buddy inspect your work because with all those lines, it's easy to miss one.

Tips & Warnings

• Working under a car is dangerous. Always wear eye protection and be sure of your lifting equipment.
• The hydraulic brakes are part of the safety equipment on an automobile. Thoroughly inspect and test the brakes before doing a road test.
