Brakes

Hydraulic Brake Inspection

Inspect the brake lever reserve before each use of the snow bike. See Brake Lever Travel.
Brake pads must be replaced when the brake pad material becomes thinner than 1/16 inch (1.5 mm). A kit is available for replacing brake pads. Your Timbersled dealer can assist.
WARNING
Brake failure during operation can result in serious injury or death. Properly functioning brakes are vital to your safety. Be sure the brake pads do not drag on the disc and that brake lever travel is not excessive. Always replace brake pads when the brake pad material becomes thinner than 1/16 inch (1.5 mm).

Excessive Lever Travel

Hydraulic brakes are self-adjusting, but if excessive brake pad clearance develops, bring the snow bike to an authorized Timbersled dealer for inspection and adjustment.

Brake Fluid

The brake fluid level can be seen through a plastic sight glass in the brake reservoir. If the fluid is sufficient, the sight glass will be black. If the sight glass is any color other than black, add brake fluid.
Replace brake fluid at least every two years with DOT 4 high temperature brake fluid, or an equivalent product.
WARNING
After opening a bottle of brake fluid, always discard any unused portion. Never store or use a partial bottle. Brake fluid is hygroscopic, meaning it rapidly absorbs moisture from the air. The moisture causes the boiling temperature of the brake fluid to drop, which can lead to early brake fade and the possibility of accident or serious injury.
WARNING
Keep the master cylinder cover free of dirt and debris. The vent slits allow for diaphragm movement, and if they become plugged, movement of brake fluid below the diaphragm may be restricted, altering brake function.
NOTICE
Brake fluid will damage labels, paint and some plastics. Always wipe up spills immediately.
