We remove the brake cylinder for replacement, as well as for replacing the cylinder repair kit
A defective cylinder is easy to detect by the presence of leakage from under the brake drum of brake fluid.
Remove the drum and brake pads (see the article - Replacing the brake drum and pads of the rear wheels).
We drain the brake fluid from the rear wheel circuit (see the article - Bleeding the brake system, replacing the brake fluid).
Holding the brake cylinder adapter with a 17 wrench, unscrew the brake pipe fitting with a 12 wrench
Disconnecting the pipeline.
With a “12” head, we unscrew the two bolts securing the cylinder to the shield
Remove the brake cylinder
Use the "17" key to unscrew the adapter
There is a copper sealing washer between the adapter and the cylinder
If the tube is tightly tightened, then you need to unscrew the cylinder fastening to the shield with the head by 12.
Pull the cylinder so that the tube comes out through the hole in the shield.
Holding the union nut of the tube with a wrench, turn the brake cylinder counterclockwise and unscrew the tube.
In this way, you can save the pipe from breakage.
After performing this operation, you need to develop the union nut of the tube, before that wetting the union nut with brake fluid.
Install the new cylinder in reverse order, replacing the copper washer.
Having installed the pads and the drum, we pump the rear circuit.
