Hi puggies, I've got a distinct loss of pedal action in the brake booster and have just replaced the quite worn hose to the intake with appropriate diameter vacuum hose that doesn't seem to have sorted it out. I have a spare booster but not sure how to test if it actually might be ok to use instead. There is no obvious leakage in the system from the resevoir although it gets topped up occasionally. I just read in the workshop manual to check belt tightness. It feels pretty good. Franzose sells new boosters. But doesn't say whether it will fit a wagon. I'm still not sure whether this car has an XN1 or 2 motor. It's a June 82 build. I guess 505 GR bits fit most in engine bay. What to do to rectify? Cheers Steven
