- Turn Valve to full increase
- Turn Valve to full decrease, counting number of turns
- Turn Valve to half the number of turns counted in step 2.
- This is your start point for adjustment
- TEST STOP YOUR COMPETITION VEHICLE. CHECK FOR ANY LEAKS ON YOUR FITTINGS
- Continue to adjust the valve, increase or decrease, so front and rear brakes stop equally (increase will allow more pressure to rear brakes)
- It is advisable to use loctite or a good quality sealant on the threads of the fitting upon installation, to ensure a leak free application.
