General Safety Instructions
Always wear eye protection when bleeding brakes.
W A R N I NG
Always wear eye protection when bleeding brakes. Failure to do this may cause
injury if brake fluid comes in contact with eyes.
N O TE
If only the front or rear half of the system has been serviced, it is usually
necessary to bleed only that half of the system. However, if a firm brake pedal
cannot be obtained after bleeding, it will be necessary to bleed the entire
system. The brake hydraulic system can be bled manually or by using a
pressure tank and adapters. Each method is outlined in the following
procedures.
Bleed brakes in the following order: right rear, left rear, right front, left front.
