Brake Pads; Brake System Bleeding - Xmotos XZ 250R Owner's Manual

BRAKEING SYSTEM Cont.
Hydraulic disc brake systems use a brake caliper to squeeze the rotors (brake disc) which causes the
motorcycle to stop. Inside the brake caliper are brake pads. The brake pads are the part of the brake system
that makes contact with the brake rotor. The pads must be checked in accordance with the maintenance
schedule for the brake system as described on page(s) 31, 32, 33. Follow the procedure below to check the
brake pad wear.
4. If you are unsure how to replace the brake pads, please contact your nearest Xmotos dealer for
assistance, or schedule your motorcycle for servicing.
BLEEDING THE BRAKE SYSTEM
Because the brake system utilizes fluid, any air bubbles inside the brake system will cause you to lose
braking efficiency. Air generally enters the brake system when the motorcycle sits unused for long periods
of time. Air will also enter the system if you have a leaking brake hose, brake caliper or master cylinder. A
brake system with air will cause the brake lever and pedal to feel soft and spongy. Use the procedure below
to bleed air from both the front and rear brake system.
NOTICE
USE ONLY DOT 4 BRAKE FLUID.
BASIC MAINTENANCE PROCEDURES
1. Inspect the brake pads
(more frequently if you do a lot of riding)
2. If the pads are worn down to a thickness of 1 mm, both
pads need to be replaced. (Never replace only one pad).
3. If you find that both pads on either front or rear caliper
are not wearing down evenly, you may need to replace
the brake pads. If one side has worn down more
extensive than the other, consult your Xmotos dealer
for a possible bad brake caliper.
1. Clean all dust and dirt from the master cylinder and
remove the master cylinder cap.
2. Pump the brake lever or pedal slowly and firmly 4-6
times and then hold it.
3. Using an 8mm wrench, loosen
located on the brake caliper. You will see brake fluid,
and possibly some air bubbles exit out the bleeder valve.
4. Tighten
or pedal slowly.
5. Repeat steps 1 – 4 until all air bubbles have stopped
flowing from the bleeder valve. The lever/pedal should
feel hard and firm when you are complete.
