Checking Brake Lever Travel; Bleeding Brake System - Arctic Cat ZR 6000 R CROSS COUNTRY Operator's Manual

2. If the brake fluid level is below the low mark,
remove the reservoir cover and add Arctic Cat
approved brake fluid until the fluid level is just
below the high mark. Install and secure the reser-
voir cover. Do not allow moisture to contaminate
the brake system.
CAUTION
Brake fluid is highly corrosive. Do not spill brake fluid
on any surface of the snowmobile.
! WARNING
Do not overfill the reservoir. Overfilling the reservoir may
cause the brake system to hydraulically lock. Use only
Arctic Cat approved brake fluid. Never substitute or mix
different types or grades of brake fluid. Brake loss can
result. Brake loss can result in severe injury or even death.
Changing
The brake fluid must be changed on a regular basis and
whenever the brake fluid has been overheated or con-
taminated. The brake fluid should be changed every
1000 miles or at the end of the snowmobiling season,
whichever occurs first.

Checking Brake Lever Travel

1. Test the operation of the hydraulic brake system by
compressing the brake lever.
2. The brake lever must feel firm when compressed.
3. To verify lever travel, compress and hold the brake
lever to its maximum resistance.

NOTE: Do not pump the brake lever as it will pro-
duce an inaccurate reading.
4. Measure the distance between the brake lever and the
handlebar. The distance must be greater than 1 in.

SNO-253
5. If the distance is less than specified, check the brake
fluid level (see Checking Brake Fluid in this sub-sec-
tion), inspect for leakage, and check the brake pads.
Do not operate the snowmobile if the distance between
the compressed brake lever and handlebar is less than
2.54 cm (1 in.). Brake loss may occur. Brake loss can
result in severe personal injury.

Bleeding Brake System

If the brake lever feels spongy when applied, the brake
system may need to be bled. To bleed the brake, use
the following procedure:
1. Remove the reservoir cover and fill the reservoir to
the high mark with Arctic Cat approved brake fluid.
Brake fluid is highly corrosive. Do not spill brake fluid
on any surface of the snowmobile.
Use only Arctic Cat approved brake fluid. Any substi-
tute may result in a loss of brakes.
2. Slide a piece of flexible tubing over the ball of the
bleeder valve and direct the other end into a con-
tainer.
3. Slowly compress the brake lever and hold. Open
the bleeder valve to release the fluid and air. When
the fluid stops, close the bleeder valve; then
release the brake lever.
