“I replaced the valve in the TR8 with a new Land Rover proportioning valve with very good results.”

Mind sharing what Land Rover prop valve you used?

Terry

The part number was mentioned earlier in the thread.

I used the LR part out of desperation because no one seemed to have them for the TR8 when I was restoring the car. Since then, they seem to have become available again - don't know why. The only TR8 valves I saw then were on eBay, and people were asking $200 and up for them. The LR valve was $90 + shipping at the time. Physically identical, although if I remember correctly one of the connections was blocked off with a pipe plug. Easily removed, so all the pipes hooked up without modification once I removed the plug.

Hello Gary,

On the uprated servo did you also install the master cylinder that goes with it? I have that servo installed on my TR7 but also installed the matching master cylinder which has a larger diameter piston. I don’t know if installing a standard TR7/8 smaller master would cause your problem but that servo (Leyland Sherpa van) originally came with the larger master cylinder. I installed it as I installed larger front calipers and wanted to move more fluid. It works perfectly.

Regards,

Terry

Vance, thanks. I now see the part number. That is for a Discovery 1.

I have a Discovery 1 and have looked at the prop valve many times wondering if it was the same casting as the TR7/8. You can buy them new for about $50. There are even aftermarket suppliers for it. I am installing disc brakes on the back of one of my wedges and will be giving that prop valve a try. Already have larger discs and calipers on the front. Thanks!
