Chevrolet Trax: Master cylinder bench bleeding
Fig. 26: Depressing And Releasing Primary Piston
WARNING: Refer to Brake Fluid Irritant Warning .
CAUTION: Refer to Brake Fluid Effects on Paint and Electrical
Components
Caution .
- Secure the mounting flange of the brake master cylinder in a bench vice
so that the rear of the primary
piston is accessible.
- Remove the master cylinder reservoir cap and diaphragm.
- Install suitable fittings to the master cylinder ports that match the
type of flare seat required and also
provide for hose attachment.
- Install transparent hoses to the fittings installed to the master
cylinder ports, then route the hoses into the
master cylinder reservoir.
- Fill the master cylinder reservoir to the maximum fill level with brake
fluid from a clean, sealed brake
fluid container. Refer to Master Cylinder Reservoir Filling.
- Ensure that the ends of the transparent hoses running into the master
cylinder reservoir are fully
submerged in the brake fluid.
- Using a smooth, round-ended tool, depress and release the primary piston
as far as it will travel, a depth
of about 25 mm (1 in), several times. Observe the flow of fluid coming from
the ports.
As air is bled from the primary and secondary pistons, the effort required
to depress the primary piston
will increase and the amount of travel will decrease.
- Continue to depress and release the primary piston until fluid flows
freely from the ports with no
evidence of air bubbles.
- Remove the transparent hoses from the master cylinder reservoir.
- Install the master cylinder reservoir cap and diaphragm.
- Remove the fittings with the transparent hoses from the master cylinder
ports. Wrap the master cylinder
with a clean shop cloth to prevent brake fluid spills.
- Remove the master cylinder from the vice.
