Wheel cylinder should be overhauled as per

recommended service schedule.

REMOVAL OF WHEEL CYLINDER (REAR)

When removing or servicing wheel cylinders, it is

necessary to drain the brake fluid from the system

and remove the brake shoes.

Attach a transparent (Vinyl) Fig. 28 bleed tube to

the bleed screw, having first removed its rubber dust

cover. Unscrew the bleed screw 1/2 to 3/4 turn and

pump out the fluid into a suitable container by

operating the brake pedal. Remove the bleed tube.

Remove the brake shoes as explained under

“Removal of Shoes”.

Remove the adaptor from the feed port along with

the gasket. Remove the wheel cylinder from the

wheel cylinder mounting bolts and take out the wheel

cylinder from the backplate. Fig. 29

DISMANTLING OF WHEEL CYLINDER

(Fig.27)

Clean the wheel cylinder externally. Remove the dust

covers fitted on the wheel cylinder assembly and

the bleed screw. Push out the pistons, and springs.

Remove the seals from the pistons and clean all

the parts thoroughly in fresh brake fluid or alcohol

and place them on a clean sheet of paper.

NEVER CLEAN THE WHEEL CYLINDERS OR

INTERNAL PARTSWITH KEROSENE OR PETROL,

AS IT WILL LEAD TO CONTAMINATION AND

DAMAGING OF RUBBER PARTS.

EXAMINATION OF WHEEL CYLINDER

Examine the cylinder bore and pistons. If they are

not scored, corroded or ridged and are smooth to

touch, new seals can be fitted. If there is any doubt

about the condition of the bore, a new wheel cylinder

assembly must be installed.
