Picked up the wagon up from the engineer yesterday. The proportioning valve had been screwed all the way in (all bias to the front brakes). Once he had screwed it midway, all was good. It's passed its tests now, with the exception of brake pedal effort and noise. The pedal effort is around 600N, and should be 300N. System has plenty of suck, but pedal effort does not decrease with the booster disconnected.
Took the wagon around to Burt Brothers. One thing I had not picked up is that if you sit there with your foot on the brake, the brake pump kicks in and does not stop running. Looks like it has a torn diaphragm. Back home again, and pulled out the booster. It was a damn sight easier putting it in before some idiot mounted everything else in the way


Changed cars, took the booster back over to Burt Bros and got there before they closed at midday. Busy morning.
Spent the afternoon pulling apart Number One Sons VL. What was described as slight brake noise turned out to be a locked front wheel, a pad with no meat left on it, and a rotor that has been eaten on the inboard face. Piston popped out of the caliper, and outer seal damaged. Looks like new pads, caliper rebuild and new rotors.
Cheers,
