Pressure Bleeding

BLEEDING BRAKE HYDRAULIC SYSTEM

Special service procedures for bleeding the brake system with the hydraulic modulator are not required.

NOTICE: Brake fluid is extremely damaging to paint. If fluid should accidently touch a painted surface, immediately wipe fluid from paint and clean the painted surface.

A bleeding operation is necessary to remove air from the hydraulic brake system whenever air is introduced into the system.
It may be necessary to bleed the hydraulic system at all four brakes when air has been introduced through a low fluid level condition, or the brake pipes were disconnected at the master cylinder. When a brake pipe is disconnected at one wheel, only that wheel cylinder/caliper needs to be bled. When pipes are disconnected at any fitting located between the master cylinder and brakes, then the brake system served by the disconnected pipe must be bled.

PRESSURE BLEEDING

TOOL REQUIRED:
^ J 21472 Bleeder Wrench
^ J 28434 Bleeder Wrench
^ J 35589 Bleeder Adapter
^ J 29532 Diaphragm Type Brake Bleeder

NOTE: Pressure bleeding equipment must be of the diaphragm type. It must have a rubber diaphragm between the air supply and the brake fluid to prevent air, moisture, oil and other contaminants from entering the hydraulic system.

1. Charge bleeder ball to 20-25 psi.
2. Connect line to adapter. Open line valve and depress bleed-off valve on top of adapter until a few drops of fluid appear.
3. Raise car.
4. Attach bleeder hose to bleeder valve and submerge opposite end in clean container partially filled with brake fluid.
5. Open bleeder valve 1/2 to 3/4 turn and allow fluid to flow until no air is seen in fluid.
6. Bleeding sequence:
A. Left front
B. Right front
C. Left rear
D. Right rear
