Replacing Rear Disc Brake Pads: Notes

Information 

• Do not open the brake system. 
• Do not loosen the brake line from the brake calliper when loosening the brake calliper. 
• The core of the warning contact wire must not be left exposed! It does not matter if the insulation is worn. 
• If necessary, remove a little brake fluid from the reservoir by suction in order to prevent an overflow when the disc brake pads are pushed back.
