Maverik Posted June 22, 2010 Share Posted June 22, 2010 Overhauling my brake system and i was wondering what my G-valve does? The workshop manual from what I can see doesn't give me much info, can anyone expand on it? Cheers mav Quote Link to comment Share on other sites More sharing options...
Gromit Posted June 22, 2010 Share Posted June 22, 2010 Is this the one on the inside chassis rail? Not 100% sure, but I seem to remember that it's something like a bias valve that limits the braking force applied to the rear circuit, to prevent the rear locking up under heavy braking.

errol209 Posted June 23, 2010 Share Posted June 23, 2010 I send you my address........ At the (small) risk of spoiling a (good) joke, the G valve has a ball bearing in it. The harder you decelerate the harder the ball is pressed forwards to try and keep the pressure in the rear circuit below the point where the back wheels will lock up. The valve is fitted at a specific angle (front end up) to stop it activating too soon. Quote Link to comment Share on other sites More sharing options...
