Has anyone out there got a proportioning valve for my fc , have a hr front end and fc rear end and the rear brakes are locking , or can i buy one from any auto shop or rare spares? Cheers Rusty Title: Re: proportioning valve Post by: sgo on January 03, 2004, 10:13:16 AM Perhaps if you had the right size rear brake cylinders you wouldn't need aproportioning valve?

This topic has been discussed numerous times; try a search of the modifications section. The rear wheel cylinders are smaller also the brake lines are a different size. John M Title: Re: proportioning valve Post by: FCwagon on January 06, 2004, 08:53:50 AM Rusty,
Fitting smaller cylinders to the rear is a bigger job than fitting a proportioning valve. The HR cylinders won't fit straight up to the FC backing plates and the HR backing plates won't fit straight on to the FC diff housing. Late Torana's have an adjustable proportioning valve which can be fitted anywhere into the rear brake line. If you're not real flash mechanically, it would be an easy job for a brake repair shop to do for you. I know a good place in Moorabbin and Hoppers Stoppers in Werribee is good. Let me know if you want the number. cheers, Leigh Title: Re: proportioning valve Post by: Phantom on January 06, 2004, 10:07:19 AM G;day Leigh,
Thanks for the info, i will chase up a late torana(what models?) valve and see if i can fit it, if i cant i have a few mates that just love doing all that stuff for a few beers and a chat. Cheers Rusty Title: Re: proportioning valve Post by: FCwagon on January 07, 2004, 09:50:46 AM Hi Rusty,
Start with UC and work back to LH if you have to, but the later model the better. Quality would be better with the later stuff too if you're sourcing from a wreckers. With any 2nd hand brake stuff it's a good idea to strip the unit & put a new kit in if needed (although there's not much in these units to give trouble) You might even try calling the local Holden dealer's spare parts or a brake specialist & see if they're still available new. I've been surprised in the past with what is actually still kept in stock and it can even work out cheaper at times. cheers, Leigh Title: Re: proportioning valve Post by: Vinnie Biankin on January 13, 2004, 12:49:27 AM Hey
Been down that road already the only reliable valve would be adjustable the ones they use in race cars and 4WD's,approx cost $360 plus fitting, i ended up picking up a HR rear end for $120 Just a bolt in and $100 for new adapted brake lines and no problem since. Hope this helps Vin |
