While planning the work, enquire on the status of parts such as the wheel cylinder or overhaul kit/seals. If there is presence of fluid on the
Brake Shoes originating from the wheel cylinder, then they have to be replaced and, in general, although only one side might be affected on the two sides of the vehicle, the shoes are replaced. This is to make certain that the correct wheel cylinder was purchased and that the wheel cylinder put in should be of the same size on each side so that equal pressure is applied when the brakes are being applied. You should start with the removal of the break drum and then try to cover the master cylinder reservoir on the case you are pulling off the brake hose, seal it with the cellophane or by clamping the flexible hose on the master cylinder brake hose clamp. Spread the brake shoes at their upper ends to provide space for the wheel cylinder to pull out and enable the holding of the automatic adjuster. Remove dirt around the hydraulic fitting in the rear of the wheel cylinder before slackening the union nut and then the two bolts joining the wheel cylinder to the backing plate, after releasing the brake pipe union nut. Disconnect the wheel cylinder from the backing plate, using clips, stuffing the open hydraulic unions with pieces of cloth to avoid dirt, getting into the cylinder and also to avoid fluid from coming out. At the time of composing this article, there were no overhaul procedures and the repair parts for the wheel cylinder, as such, it is advisable to replace the entire wheel cylinder. Remove the plug of the hydraulic pipe and back up the backing plate and ply the RTV sealant at the wheel cylinder-to-backing plate surface and then fit the cylinder securely and then fasten the hydraulic fitting nut with hand-tightening. Torque the mounting bolts and go on to engage the hydraulic union nut and bring it to the required torque. Pull the plunger rod of the automatic brake adjuster mechanism to pull the brake shoes closer to the wheel cylinder pistons by applying some force and exerting pressure on the adjusting knob, which is located at its extreme end and turning it anti-clockwise to its minimum extent. If necessary, pull off the clamp of the flexible brake hose or cellophane of the master cylinder, and then put on the
Brake Drum. Drain out the hydraulic system, meaning which appropriate measures should be taken to reduce the loss of the fluid, it should only be necessary to drain out the relevant back brake. Last but not the least, test the brakes again with a lot of caution before the car is put back to standard use.
