Assembly and Installation

Remove Air from the System

(“Bleed” the Brakes)

WARNING

You must bleed the brakes to remove all air from

the system, when you loosen any brake system

hydraulic connection. Air can prevent hydraulic

pressure from applying the brakes properly and

can increase stopping distance. Serious personal

injury and damage to components can result.

Use only the type of hydraulic fluid specified by

the equipment manufacturer. Do not use or mix

different types of hydraulic fluid. Using incorrect

hydraulic fluid will damage the rubber parts of the

caliper. Loss of braking control, serious personal

injury and damage to components can result.

Do not reuse hydraulic fluid. Used fluid can be

contaminated and can cause incorrect operation.

Serious personal injury and damage to

components can result.

1. Check that the master cylinder is filled to the

correct level with hydraulic fluid specified by

the component manufacturer. Keep the master

cylinder filled when you bleed the brakes, so air

does not enter the system through the master

cylinder.

2. When you have finished bleeding the brakes,

check that the master cylinder is filled to the

correct level.

3. Put a clear tube on the bleeder screw.

Submerge the opposite end of the tube into a

clear container of the specified hydraulic fluid.

•

HDB 640 and SCL 53 dry disc brakes are

designed to bleed correctly when mounted at

the three, nine and twelve o’clock positions.

•

SCL 35 and SCL 46 dry disc brakes are

designed to bleed correctly when mounted in

the three and nine o’clock positions.

4. Always start at the point in the system that is

farthest from the master cylinder and work

back toward the master cylinder.

5. When you complete a bleeder screw: Go to

the next closest bleeder screw on the same

caliper.

6. When you complete a caliper: Go to the next

closest caliper on the same wheel.

7. When you complete a wheel: Go to the

farthest bleeder screw on the next closest

wheel.

8. Follow the instructions below to bleed the

brakes.

Full Hydraulic Systems

1. Slowly apply low hydraulic pressure to the

caliper. Loosen the bleeder screw.

2. Continue to apply pressure until there are no

air bubbles in the hydraulic fluid.

3. Tighten the bleeder screw to 100-180 lb-in

(11.3-20.3 N•m). Release the pressure to the

caliper.

4. Check for fluid leaks.

Air Hydraulic or Mechanical

Actuator Systems

1. Apply the brake pedal. Loosen the bleeder

screw.

2. Tighten the bleeder screw 100-180 lb-in

(11.3-20.3 N•m) before you release the brake

pedal so that air does not enter the system.

3. Repeat until there are no air bubbles in the

hydraulic fluid when you apply the brake

pedal and loosen the bleeder screw.

4. Check for fluid leaks.
