The New Parts The Old Parts Clean up Re-assembly Front Caliper Hoses
Old Parts
- The drum retaining screw can be difficult to remove when rusted in place, or in the xase with these, sealed
- with loctite !! I use a tight fit cross head bit and tap it with a hammer which normally disturbs it enough to
- unscrew easily.
- The caliper has to be un-bolted to replace the discs, but in my case I disconnected the brake pipe feed
- and capped the end so as not to lose brake fluid. I had also clamped the flexi hose, but these were to
- be replaced aswell, so I needed the extra leak stop.
The shoes and retaining parts removed, notice the adjuster at the top, the star wheel can be turned
via access through a hole in the drum, often if the shoes have made a ridge in the drum the adjuster
will need to be backed off before the disc can be removed. The shoes were not actually in bad
condition.
- These two rectangular holes either side of the backplate are used to push the pin through (has a square
- lug on the end) which holds the shoes against the backplate, often the back plate gets so rusty along with
- the pins that the just pull through, then the shoes jam inside the drum. Thankfully these are in good shape.
Urrhhgg !, quite a state the pistons, these were originally chrome plate, which is all gone where the pistons pertrude.
No better after a clean up........
Twist with a pipe wrench and the old pistons easily pull out
I am quite sure had I pushed these back in to replace just the brake pads, the rusted area's would have damaged the
seals and allowed brake fluid to piss out !
