Brakes
Brake Inspection
1. Check the brake system for fluid
leaks.
2. Check the brake pedal for
excessive travel or a spongy feel.
3. Check the friction pads for wear,
damage and looseness.
4. Check brake discs for signs of
cracks, excessive corrosion,
warping or other damage. Clean
any grease using an approved
brake cleaner or alcohol.
WARNING! Do not apply WD-40 or any
petroleum product to brake discs. These
types of products are flammable and may
also reduce the friction between the brake
pad and caliper.
5. Inspect the brake disc spline and pad wear surface for excessive
wear. Change pads when worn to 0.030" (0.762 mm).
