Hi guys,
I have a 2001 Mitsubishi Mirage that I am using as a track car.
It has been on a brake roller test and the brake bias is 91F/9R which doesn't sound right.
The brakes have been upgraded including
Different BMC and booster
Larger twin pot front calipers (from single pot)
Drum to disc rear conversion
At first I suspected (as is often the case) that the brake prop valve is designed for drum rear brakes and swapping that for one from a rear disc equipped vehicle would rectify this but after some research the part numbers between cars that have discs and ones with drums at the back are the same.
My next action is to open up the rear calipers to make sure nothing is stuck (seeing as these came off of a wreck with unknown history) but I don't expect to find an issue.
Any ideas of what could this be?
All lines seems fine.
Also is there a way to bench test a prop valve to see what the bias is?
