Improper assembly of the wheels or malfunction of the brake system may be extremely hazardous and could cause accidents, even fatal ones. Be sure to learn the proper braking technique and operation of your bicycle. [. . . ] This can force dirt into parts of the hydraulic braking system, which may cause damage. It is essential that the rotor is clean (free from grease or oil residues) to avoid contaminating the brake pads and insure perfect braking. To avoid brake fluid spillage on the rotors or brake pads, causing contamination of the brake pads, it is advisable to cover the vital parts with a rag before maintenance of the hydraulic system is done, or when lubricating parts of the bike. If brake fluid comes in contact with paint or plastic bike parts, wipe it off immediately. If you get any brake fluid on the brake pads, discard them and replace with new pads. The fluid in this braking system (use DOT 4 or DOT 5. 1 brake fluid only!), besides possibly damaging the paintjob and some plastic parts on the bike, is extremely hazardous in case of contact with eyes or skin. We recommend to replace the brake fluid in the system at least every 2 years. This fluid naturally absorbs water, which will result in a lower boiling point for the brake fluid and can cause poor braking. After riding (off road) in the dirt, clean the bike (and the components of the braking system) as usual with water, soap, washing-up liquid, etc. After washing the bike or riding in the wet, take the wheels out of the bike. If the wheels remain in the bike, water may stay between brake pads and rotors and cause corrosion. After wiping dry with a clean soft cloth, remove all dirt from the brakes with a soft brush. Turn the adjust knob of the master cylinder clockwise until you see there's no clearance between brake pads and rotor. Turn the adjust knob of the master cylinder anti-clockwise and pull the brake lever until you find the best braking position on your hand. Note: Do NOT use MPH brake pads "model year 2000" (2 holes in each pad). These pads do not fit into the MPH-2 (model year 2001) and MPH-3 (model year 2002) calipers. For example: After replacement or disassembly of : brake lever or caliper or hose or bleeder After shortening a hose Lack of brake fluid in MPH brake system due to leakage Replace brake fluid for MPH at least every two years When the braking systems feels spongy, perhaps there is air inside the hydraulic system. Advice: It's better to remove wheels and brake pads before working with brake fluid. Leakage of brake fluid on brake pads or rotor will ruin these parts. 1. Turn the adjustment knob of the fluid reservoir on the brake lever anti-clockwise all the way to create max. Allen-key to unscrew the M5 lock screw from the master cylinders' fluid reservoir. Connect the short, transparent tube on the fluid reservoir / master cylinder, by screwing the connector (brass colour) in the threaded hole for the lock screw. If it's too tight, the connectors' rubber O-ring will be deformed too much and it will leak air and fluid. - Pag. [. . . ] - 6. Trouble shooting and -prevention When riding down a slope, continuous braking with MPH disc brake will generate a lot of heat. 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. That will lead to distortion of the rotors and change the characteristics of the materials. [. . . ]
