I have no idea how to test one, but they are known for seizing up. I plan to bin mine and put in a bias valve to the rears. Fastest 998 mini in the world? 13.05 1/4 mile 106mph

could you explain how they work? is it just a basic 60/40 % type thing? or is more a regulator only letting a set psi to the back

How much was the willwood though? If something is worth doing, it's worth doing half of. |

Get it from rally design for £60. From memory the post wasn't expensive and it arrived quickly. On 11th Feb, 2015 robert said:

Thread revival but is this still seen as a good solution or has there been any developments since? Price has gone up but is still still the best option? Has anyone had any issues using the Wilwood setup? Thanks Edited by Amp on 17th Jun, 2020. |

If you want to test the PDWA (pressure deferential warning actuator) thing on the bulkhead, disconnect one of the front brake pipes from one of the caliper. You should still get some braking effort from the other 3 brakes when you press the pedal. Obviously don't do this on the road/driving. |
