Brake Bleeding: Service and Repair
With ABS
FRONT BRAKES
The front brakes can be bled in the same manner as conventional brakes, with or without the accumulator being charged.
REAR BRAKES
If the pump motor is allowed to operate continuously for approximately 20 minutes, a thermal safety switch (inside the motor) will
automatically shut off the motor. A 2 to 10 minute cool down period is typical before normal operation can resume. Exercise care when opening
the rear caliper bleeder screws, due to the high pressure available from a completely charged accumulator at the bleeder screws. Serious injury
may result if care is not taken.
Bleeding w/Accumulator Charged
1.
With accumulator pressure applied to the system, bleed rear brakes by opening rear brake caliper bleed screws for 10 seconds at a time while
applying brake pedal with ignition switch in Run position.
2.
Repeat step 1 until air-free flow of brake fluid is observed at each caliper.
3.
Close bleed screws, then pump brake pedal several times.
4.
Adjust brake fluid quantity in reservoir to MAX level with accumulator fully charged.
Bleeding w/Pressure Bleeder
1.
Attach Rotunda bleeder No. 104-00064, or equivalent, to reservoir cap opening and apply a minimum pressure of 35 psi to system.
2.
With brake pedal at rest and ignition switch in Off position, open rear caliper bleed screws for 10 seconds at a time.
3.
When an air-free flow of brake fluid is observed at each caliper, close bleed screws and turn ignition switch to Run position.
4.
Pump brake pedal several times, then adjust brake fluid quantity in reservoir to MAX level with accumulator fully charged.
