Bleeding Procedure - Giant MPH-3 - MODEL YEAR 2002 Owner's Manual

5.3 Bleeding procedure

When to bleed ?
Whenever the system lost brake fluid or air came into it.
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. volume inside the
reservoir.
At least 10 full turns.
2. Use a 3 mm. Allen-key to unscrew the M5 lock screw from the
master cylinders' fluid reservoir. Remove screw, cap and O-ring.
3. 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.
Do this by hand and no too tight. Don't use a tool. If it's too tight,
the connectors' rubber O-ring will be deformed too much and it will
leak air and fluid.
