I've been rebuilding the front brake hoses today and I've come across 2 issues. It an imperial 1999 chassis with widetrack suspension and std brake calipers. 1. Regarding the fitting of the caliper banjo bolts, the Assembly guide refers to a thick and thin copper washer that is fitted either side of the banjo. I need to order these, but the Caterham parts site only refers to one washer which, it says is fitted either side - here. Have things moved on and I just need two if these - one either side of the banjo on the bolt? Or are there part numbers for the thick and thin washers that I haven't been able to find? There is nothing in my De Dion parts manual. 2. At the inboard end of the hose, I am finding that the brake pipe nut on the rigid pipe is hitting / fouling on the flexi pipe nut before the rigid pipe nut is properly snugged down. It's as if there isn't enough thread left on the flexi hose once I add the washer either side of the ally skin and the shakeproof washer and then the hose securing nut. I've compared against my original hoses and they look the same so I'm not sure why this is happening, unless either (a) it was fouling before and I didn't notice (i didn't build the car) or (b) I'm, using thicker washers either side of the skin... Can anyone help with either issue please?
