NOTE: Brake fluid replacement procedure explained in this article is for the brake fluid in the modulator unit (that is, the brake fluid in the
high-pressure passage and in the reservoir). Refer to Brakes, Service & Repair for the brake fluid replacement procedures for the rest of the brake
system. See: Brake Bleeding/Service and Repair/Bleeding Procedures
1. Start the engine and let it idle for a minute. Stop the engine.
2. Check the brake fluid level in the reservoir. It should be below the MAX (upper) level line.
3. Use the steps below to drain the rest of the brake fluid from the modulator unit.
NOTE: Approximately 35 - 45 ml (1 1/6 - 1 1/2 fl. oz) of the fluid is drained at each try.
A) Attach a wrench to the maintenance bleeder.
B) Connect a rubber tube of the appropriate diameter to the maintenance bleeder, and set the other end of the rubber tube in a suitable container.
C) While holding the rubber tube with your hand, slowly loosen the maintenance bleeder 1/8 to 1/4 turn to collect the brake fluid in the container.
CAUTION: Do not loosen the maintenance bleeder too much. The high-pressure brake fluid can burst out.
D) Start the engine and let it idle for a minute. Stop the engine.
E) Check the brake fluid level in the reservoir. It should be below the MAX (upper) level line.
F) Tighten the maintenance bleeder.
