i'm bolting it all on hopefully on tuesday
i have 2 outputs from the master cylinder, 1 is going into a T piece and then to the front 2 calipers, the second is going under the car and then up into the cabin, into the valve and back out under the car into a T piece then to the rear brakes, well thats how i understand it to work anyway!
the 172 cup has 4 outputs off the master cylinder IIRC (172 and 182 with ABS have only 2) so i guess you need to take the 2 rear lines into a Tpiece, then into the valve then out into a second T piece to the rear calipers
the Tilton valve is basically a pressure reduction valve, on position 1 maximum pressure goes to the rears (same pressure as the fronts get) but on position 7 the flow is restricted, so less pressure goes to the rear
hopefully i've got that right, if i'm on here posting on Tuesday night i will have got it correct! LOL
