Suzuki GSX-R 1000 Service Manual: Rear brake master cylinder assembly removal and installation
Refer to “rear brake hose routing diagram” (page 4a- 2).
Removal
- Remove the right side frame cover. Refer to “exterior parts removal and installation” in section 9d .
- Remove the rear brake fluid reservoir mounting bolt (1).
- Drain brake fluid. Refer to “brake fluid replacement” .
- Place a rag underneath the brake hose union bolt (2) on the master cylinder to catch any spilt brake fluid.
- Remove the brake hose union bolt (2).
- Loosen the lock-nut (3).
- Remove the master cylinder mounting bolts (4).
- Remove the master cylinder along with the reservoir by turning the push rod (5).
Installation
Install the rear brake master cylinder in the reverse order of removal. Pay attention to the following points:
| Caution the seal washers should be replaced with the new ones to prevent fluid leakage. |
- Apply thread lock to the master cylinder mounting bolts (1) and tighten them to the specified torque.
: Thread lock cement
99000–32110
(thread lock cement super “1322” or
equivalent)
- Tighten the lock-nut (2) temporarily.
- After setting the brake hose union to the stopper, tighten the union bolt (3) to the specified torque.
Tightening torque rear brake master cylinder mounting bolt (a): 10 n·m (1.0 Kgf-m, 7.0 Lbf-ft) brake hose union bolt (b): 23 n·m (2.3 Kgf-m, 16.5 Lbf-ft)
- Bleed air from the brake system after reassembling the master cylinder. Refer to “air bleeding from brake fluid circuit” .
- Adjust the brake pedal height. Refer to “brake pedal height inspection and adjustment” .

Brake pad
Front
Rear
Inspect the front and rear brake
pads to see if they are worn down
to the grooved wear limit line 1. If
a pad is worn to the grooved wear
limit line, it must be replaced with
a new one. After replacing either
the front or rear brake pads, the
brake lever or pedal must be
