    I’m trying to see if I could get an adapter for the master brake cylinder in a London Roadster for a Speedi-Bleed kit.  Yet it has been years since I’ve driven it and it’s going to need a lot of attention when I get some time in the fall or a few cool hours in the early morning this time of year.  Where can I find the master brake cylinder in the LR, please?

    The sure way to find it is to start at the driver’s side from wheel and trace the brake line until you get to the thing with all the other brake lines coming out of it. There will be two bolts fastening it to a bulkhead. In a VW pan that would be the “Napolean’s Hat” cross member just behind the front wheels. I think your chassis is custom but the location—whether hat shaped or not—should be right about there. It’s not so easy to get to.

    Good luck.

    mglondonroadste. If your brake master IS mounted to the VW frame head (Napolean’s Hat) you need to disconnect the MC bolts from the inside but DO NOT pull them out all the way. The frame head piece is double-walled with a spacer sleeve over the bolts between the walls (to prevent buckling should the bolts be over torqued.) If you pull the MC mounting bolts completely out those spacer sleeves won’t come with the bolts and will drop to the bottom of the pan. And getting them back up into position will be nearly impossible and you may end up with an annoying rattle up front. Best to disconnect the brake lines from the MC, (don’t forget the brake light wires), then thread the bolts out until the MC just comes loose and leave the bolts in the frame head. This is also a good time to check the hose(s) from the MC to the brake reservoir and change them if needed.
