1. Start the engine, and let it warm up to operating temperature.
2. Attach a 50 mm (2 in.) piece of masking tape along the bottom of the steering wheel, and draw a horizontal
reference mark across it.
3. With the transmission in Neutral, press and hold the brake pedal lightly (about the same pressure needed to keep
an A/T-equipped car from creeping). Then release the parking brake.
4. While still holding the brake pedal, hook the end of the tape measure behind it. Then, pull the tape up to the
steering wheel, noting where the tape measure lines up with the reference mark you made on the masking tape.
5. Apply steady pressure to the brake pedal for 3 minutes.
6. Watch the tape measure.
• If it moves less than 10 mm (0.4 in.), the master cylinder is OK.
• If it moves greater than 10 mm (0.4 in.), replace the master cylinder.
