Brake/Clutch Fluid
The brakes and clutch draw fluid from the same reservoir.
Inspect the fluid level in the reser-
voir regularly. It should be kept
between the MAX and MIN lines.
The level normally drops with
accumulated distance, a condition
associated with wear of brake and
clutch linings. If it is excessively
low, have the brake/clutch system
inspected by your Toyota dealer.
Inspecting Brake/Clutch Fluid Level
