CAUTIONS & WARNINGS
Only after the accumulator is discharged can the adapter and the pressure gauge be safely
installed or removed. Failure to heed this warning could result in personal injury to yourself, others
or damage to me vehicle being worked on.
Before disconnecting any lines, installing any adapters or performing any pressure checks or other
work at the master cylinder, the accumulator must be discharged and the system depressurized. To
discharge the accumulator, turn the ignition key to the off position; next pump the brake pedal for
25-35 times until it becomes rock hard, men pump me pedal an additional 5 times.
Care must be used not to get any brake fluid on any portion of me vehicle. Even the black bumpers
on some vehicles can be discolored by contact with brake fluid, even if it's only off a person's
hands. Never allow brake fluid to spill onto anything you care about as the caustic nature of the
fluid will cause damage. Appropriate care should be observed at all times. Brake fluid can easily
damage painted and other surfaces of the vehicle.
Brake Fluid should be handled with care and caution. Always wear appropriate protective gear
when using this equipment. Personal injury and vehicle damage could easily result by brake fluid
contacting a person (such as getting brake fluid splashed or sprayed into your eyes) or by having
brake fluid contact the painted surface of the vehicle. Water is a common flushing agent for DOT-3
or DOT-4 brake fluid.
Do not over pressurize the gauge assembly or accuracy will be lost.
Always wear approved protective safety glasses when testing the pressure of brake systems.
Should brake flu id get into the eye(s), flush the eye immediately with lots of water and consult your
physician. Should irritation persist, see your physician immediately.
INTRODUCTION & GENERAL INFORMATION
Some vehicles have their rear ride height proportioning valve adjustments made with the weight of the
vehicle off the tires.
Pressure checks for the base system operation should be done with the weight of the vehicle on the
tires, unless specific OE manual instructions state otherwise.
This will simulate the actual pressure being applied to the rear wheels under actual vehicle operating
conditions.
The vehicle should be carrying its normal load to allow you to check the pressures that are on the rear
brakes during normal vehicle operation.
•
Disc brake systems should not have any residual pressure.
•
Rear brake pressures will normally be lower than front brake pressures.
•
Drum brake systems may have residual pressure after the brake pedal is released
•
Rear pressures may be 60-80 of the front pressures.
With a firm force on the brake pedal, common hydraulic pressures at the wheels should be in the 700
to 1500 psi range.
This will vary greatly depending on the vehicle and the exact amount of force on the brake pedal, but
it should normally fall within this range.
No matter what the configuration of the system, front to rear or diagonal split, the hydraulic brake fluid
pressure at both front wheels should be the same; likewise, the pressure at both rear wheels
should be the same. (If pressures are within 10 side to side, they fall in an acceptable range).
On vehicles with rear ride height proportioning valves, always check the rear pressure with the vehicle
resting on its tires and with a normal load in the vehicle.
If checked with the tires hanging, such as if you have the vehicle on a hoist, little if any rear brake
pressure will be present.
