porsche Posted December 17, 2012 Share Posted December 17, 2012 As you know I am doing a new build , I know the old disco inside out , but the 90 is a learining curve , so , from master cylinder do the pipes go to prv or just to brakes direct , I have the master from the 90 and a prv from the disco , still using disco brakes and axles , if it has a prv where is it mounted ? Thankyou in advance . Quote Link to comment Share on other sites More sharing options...
western Posted December 17, 2012 Share Posted December 17, 2012 Pressure Reducing Valve is attached to the bulkhead below the brake servo/brake pedal unit. layout for a 300tdi 90 on attached diagram. Quote Link to comment Share on other sites More sharing options...
oneandtwo Posted December 18, 2012 Share Posted December 18, 2012 I will take some photos tonight, I have just made all new brakepipes in Kunifer exactly replicating the factory ones. You have to blank one port of the disco PRV to use on the 90. Quote Link to comment Share on other sites More sharing options...

oneandtwo Posted December 18, 2012 Share Posted December 18, 2012 Quite hard to take a photo as it's all tucked away. Brake pipes are to factory layout. (PS Yes I know the steering UJ is missing a bolt) Quote Link to comment Share on other sites More sharing options...
porsche Posted December 18, 2012 Author Share Posted December 18, 2012 Thats brill , do you know where about in footwell the bolt comes through to secure to bulkhead as I`ve put a new footwell in < Quote Link to comment Share on other sites More sharing options...
porsche Posted December 18, 2012 Author Share Posted December 18, 2012 got it now , what do you blank off with , is it just a male blank ? Quote Link to comment Share on other sites More sharing options...
oneandtwo Posted December 18, 2012 Share Posted December 18, 2012 That's a proper 90 PRV, It has one port which is undrilled, wheras the disco one is drilled. I guess you could use a proper blanking plug off a spare 90/disco rear caliper Quote Link to comment Share on other sites More sharing options...
