Bleeding Brake System - Arctic Cat Wildcat EFI 1994 Service Manual

Arctco recommends the removal and disassembly
of the brake caliper assembly when changing the
brake fluid (see Caliper section).
Brake fluid is highly corrosive. Do not spill brake
fluid on any surface of the snowmobile.

WARNING
Use only Arctco approved brake fluid (pIn 0638-315).
Any substitute may result in a loss of brakes.

2. Slowly squeeze the brake lever and hold. Open
the bleeder valve to release the fluid and air.
When the fluid flows free of air bubbles, close
the bleeder valve; then release the brake lever.
3. Add new Arctco approved brake fluid (pIn 0638­
315) to the reservoir and repeat step 2 until the
brake fluid flows free of air bubbles and
appears clean.

WARNING
Do not use brake fluid from a container that has
been opened for a long period of time. Unsealed
brake fluid containers will absorb moisture and can
contaminate the fluid inside.
NOTE: It may be necessary to refill the res­
ervoir several times to eliminate all con­
taminated brake fluid.
4. When the brake fluid is free of all air and con­
tamination, and the brake lever feels firm when
compressed,
fill
the reservoir to a level just
below the high mark; then install and secure the
cover. Remove the tube from the bleeder valve.
BLEEDING BRAKE SYSTEM
If the brake lever feels "spongy" when applied, the
brake system may need to be bled. To bleed the
brake system use the following procedure:
1. Remove the master cylinder reservoir cover
and fill the reservoir to the upper mark with
Arctco approved brake fluid.
Brake fluid is highly corrosive. Do not spill brake
fluid on any surface of the snowmobile.
