    Default DS rear brake

    I noticed the rear brake has some green wetness.
    What should I check? An easy fix?

    The wheel cylinder inside the drum. It's a normal wheel cylinder but uses LHM instead of brake fluid. It probably needs a seal kit.

    You might start with the seal where the pipe enters the cylinder. Is it wet? Or the bleeder nipple?

    Too late!! Direct access like 3 intravenous feeds. A necessary life support system. A friend often asks me "which patient is it today?"

    its leaking from the bottom of the drum as far as I can tell. So sounds like a seal kit is required?

    Yes, you probably need a seal kit. Remove the drum and have a look. It's not hard. Remove road wheel. Undo the two screws that hold the drum to the hub. Pull off drum. You may need to free the drum. Whack it with a rubber hammer if you have to. If you don't have a rubber hammer then hold a piece of soft wood to the drum and whack that. Start gently. Whack the side of the drum, at various places around its edge. Do not lever the drum, you will bend or break something. Once you have the drum off any leaking LHM will be obvious.

    If the wheel cylinder is leaking I would suggest you do up both rear brake cylinders.

    don't forget to back the brake adjuster off first

    D rear brakes are some of the simplest to work on. no millions of springs and levers like most rear drum vehicles have with the handbrake incorporated.

    DO NOT loosen the locking plate or move the brake shoe cam adjuster unless you have a brake lining centreing tool.
    Without this tool, you will more likely than not, if you move the cam adjusters, put the linings out of adjustment.

    You can easily remove the shoe springs and access the wheel cylinder, without disturbing the shoe adjustment.
    Most D's I've seen have the rear brake shoes out of adjustment. Without the tool it's a hit or miss adjustment at best.
