Title: Thread size on a '67 master cylinder - Disk Brake Questions..! Post by: SteveW on June 03, 2008, 18:57:11 pm Does anyone know the thread size of the ports on a '67 beetle master cylinder? I want to run AN fittings throughout so I need to order the correct adapters!
Thanks Steve Title: Re: Thread size on a '67 master cylinder Post by: JS on June 03, 2008, 20:25:27 pm Should be M10x1.

Title: Re: Thread size on a '67 master cylinder - Disk Brake Questions..! Post by: SteveW on June 04, 2008, 15:56:47 pm As I'm going to be running 4 wheel disk brakes, is it a good idea to run a brake proportioning valve e.g this from Wilwood
(http://www.rallydesign.co.uk/images/knobvalve-SML.jpeg) Also do I need to run a residual pressure valve as the M/C will be lower than the calipers?

Post by: Zach Gomulka on June 04, 2008, 16:14:52 pm I've got 4 wheel discs on my car, original master cylinder with no residual pressure valve and no problems. I am thinking about installing a proportioning valve though because when I really hammer on the binders my 145's lock up, a little more bias towards the rear wouldn't hurt.
