Trouble shooting and -prevention
When riding down a slope, continuous braking with MPH disc
brake will generate a lot of heat. The heat will be conducted to
the brake fluid. The temperature of fluid can increase up to
120º C. or more. As shown in the illustration, the stroke of
brake lever will become shorter.
When this happens, the rider MUST stop riding to let the
brake system cool down. No liquid shall be used to cool the
brake components.
That will lead to distortion of the rotors
and change the characteristics of the materials.
Meanwhile, the rotors and the calipers should NOT BE
TOUCHED, because they can be very hot.
If the rider keeps using the brakes, the brake fluid will be
heated to 150º C. or more. Then the brake pads will wear out
very quickly.
If the pads are worn, the brake force is decreased, even if the
brake lever is pulled completely to the handlebars (see
illustration on the left).
This is extremely dangerous.
After the temperature has reduced, the adjuster on the brake
lever can be turned clockwise to bring the brake pads closer
to the rotor (to compensate the pad wear out).
Parts:
Brake pads
When to change?
Before each ride, check the wear pattern of the pads (both front and rear).
The back plate of the brake pad should not touch the rotor.
Replace the pads if there is not enough material left,
or if high frequency noise occurs during braking.
How to change?
See: “Maintenance; replacement of brake pads”.
Remarks:
Only use MPH genuine parts.
Do NOT use MPH brake pads “model year 2000” (2 holes in each pad).
Two pads must be replaced at the same time.
