CHT857 BRAKE BLEEDER
1. Ensure that the brake bleeder is clean and free from old brake fluid.
2. Remove the hydraulic fluid reservoir cap from the vehicle. If old fluid is
contaminated, drain it off and refill the system with fresh fluid.
3. Firmly screw the bleeder cap (12) onto the vehicle hydraulic fluid reservoir,
ensuring that the gasket seats correctly.
4. Make sure that the quick-release coupling (13) of the container hose (2)
and cap (12) are clean. Pull back the collar of the quick coupler and push
the adapter into it. Release the collar to lock the two together.
5. Place the brake bleeder in a stable location in the vehicle engine bay and
tighten the bleeder cap (6). Commence pumping the hand pump (3) to
pressurize the system to approx 10 psi (0.7 bar) as indicated by the gauge.
6. Check for leaks at the cap (12) and at the hose (2) and if leaking, release
the pressure in the bleeder by gently unscrewing the pressure release valve
(5). Re-fit the cap and hose and pressurise again.
• DO NOT remove the container cap before depressurising the bleeder.
7. If leak free, release the pressure, unscrew the bleeder cap (6) and add
new hydraulic fluid of the type recommended for your vehicle. to the
bleeder container.
8. Tighten the bleeder cap and pressurise the bleeder.
• DO NOT exceed 20 psi (1.4 bar). Higher pressures may damage your
vehicle hydraulic system and could result in injury.
9. Determine the correct brake bleeding sequence from your vehicle service
manual.
10. Attach a bleed tube (not supplied) to the bleed nipple at the first wheel
cylinder to be bled. Place the free end into a container. Open the bleed
nipple and wait until fluid runs clear and free of bubbles, then re-tighten
the bleed nipple.
11. Repeat on each bleed nipple, restoring pressure in the bleeder if
necessary. When complete, release the pressure by loosening the pressure
release valve (5).
12. If, when finished, fluid remains in the bleeder container, open the bleed
valve closest to the vehicle master cylinder until the fluid drops just to the
maximum fill level on the reservoir. Close the brake bleed valve.
13. Remove the bleeder cap (12) from the fluid reservoir, taking care to avoid
spilling any fluid remaining in the hose.
14. Replace the reservoir cap on the vehicle, checking that the fluid level is at
the maximum level indicated on the vehicle reservoir.

driving the vehicle,
CHT858 RESERVOIR ADAPTER
If the 44mm bleeder cap (12) does not fit the vehicle hydraulic reservoir, the
CHT858 adaptor will be required.
1. Fit the reservoir adapter over the reservoir filler neck.
2. Pass the chain (10) under the hydraulic reservoir, of the vehicle and attach
to both "J" hooks (11). Turn the two tensioning nuts (8) equally to tighten the
Reservoir Adapter to the reservoir rim to seal the system.
3. Make sure that the quick-release coupling (13) of the container hose (2)
and adapter hose (9) are clean. Pull back the collar of the quick coupler
and push the adapter into it. Release the collar to lock the two together.
4. Place the brake bleeder in a stable location in the vehicle engine bay and
commence pumping the hand pump (3) to pressurize the system to
approx 10 psi (Do not exceed 20 psi).
5. If the system does not hold air pressure, adjust the adapter and retighten all
connections, then try again.
6. Follow the procedure on page 6 from step 5 onwards.
TROUBLESHOOTING
CARE AND STORAGE
