We replace the hoses in case of cracks, swellings, and also after 5 years of operation.
There are times when the hose collapses inside, making it difficult for the passage of brake fluid
This causes a wedging defect in the caliper.
Intensive wear of the brake pads and brake disc occurs, with significant heating.
We drain the brake fluid (see the article - Bleeding the brake system, replacing the brake fluid).
Holding the tip of the brake hose on the outside of the frame with a “17” wrench, unscrew the tube fitting from its inner side with a “12” wrench or a special key (the wheel is removed for clarity).
Use pliers to remove the locking spring plate, and remove the hose from the hole in the frame.
If it is not possible to unscrew the brake pipe fitting in this position, remove the locking plate and bring the hose tip together with the tube into the wheel arch, where, holding the tip with the “17” key, unscrew the tube fitting with the “12” key.
Using the “17” key, unscrew the second hose tip from the brake cylinder and remove the hose
There is a copper sealing washer between the hose end and the cylinder.
Install the new hose in reverse order, replacing the copper sealing washer with a new one.
After filling in the working fluid and bleeding the system, check that there are no bulges on the hose and brake fluid leaks from the connections.
