Brake pads
The pads sit in the caliper through which the brake disc passes. Shine a torch into the caliper and look at the thickness of the friction material. Many pads have a groove in the lining – a wear indicator. When the groove disappears or the lining is only a few millimetres thick, it is time to replace them.
Never wait until the pads wear down to the metal. Then the brakes squeal, brake poorly, and the metal destroys the disc, which is considerably more expensive to replace.
Brake discs
- The surface should be smooth and evenly shiny.
- Deep grooves or blue discolouration from overheating are a reason for a check at the workshop.
- If the lever or pedal pulses when braking, the disc may be warped.
- Never spray chain lubricant or preservative sprays onto the discs.
Brake fluid
Brake fluid is hygroscopic – it gradually absorbs moisture from the air. This lowers its boiling point, and under heavy braking, for example on a descent, the brake can go “soft”. That is why the fluid is changed according to the service schedule, usually every two years (the exact interval is in the service book), even if the level does not drop.
Check the level in the transparent reservoir on the handlebars (front brake) and, for the rear brake, in the reservoir by the right footpeg. The level should be between the MIN and MAX marks. Dark, brown fluid should be replaced.
Watch for a falling level
The level naturally drops slightly as the pads wear. But if it falls quickly or you see fluid around the caliper or hoses, there is a leak. Do not ride the motorcycle in that condition and have it checked.
How the brakes should work
- Both the lever and the pedal have a clear, firm point of engagement.
- The brake releases after you let go and the wheel turns freely.
- The motorcycle does not pull to one side when braking.
- The ABS system goes through a short test after starting and the warning light goes out after you pull away.
If the ABS light comes on while riding or the brakes do not respond as they should, do not wait. At Royal Enfield GARAGE we check the brakes, replace the pads or fluid and bleed the system.
