Parking brake

The conversion from drum brakes to disc brakes in the rear means I cannot use the same parking brake cables. After having studied lots of pictures of disc parking brakes last summer I thought I needed to custom build a cable and connection to the parking brake lever. This made med postpone the decision on how to do it.
This summer things suddenly looked better. I discovered that there apparently is a model of the A2 with disc brakes. I don't know if it has ever been sold in Sweden or elsewhere, but its parking brake cables are available as spare parts.
So after taking a chance on which cables to use I ordered them from the Audi dealer and I was able to mount the cables which fitted almost perfectly. I just had to trim the hand brake lever on the calipers with a drill so that the cable would fit.
I believe it was pure luck that the cables had the right length. The length is just right because of the angle at which I mounted the rear disc calipers. This was made just by looking at pictures of other cars!
The parking brakes work. But after driving the car without using the parking brake for half a year, it jams a bit. So I think a need to jog it back and forth for a while with some thin oil.

Ups and downs and poor suppliers

Today I had some ups and some downs.
I got the used calipers for Skoda Fabia from a scrap yard today. It tuns out one of the calipers won't fit the Fabia spindles. That one didn't have a tag so I guess the whole caliper might come from a different VAG car. Just to send it back...

The two calipers. Note the huge difference in distance between the mounting holes. The one on the right fits, the left one does not.

I also started taking off the right spindle without luck. First the screw for the rotor broke so I will have to get a screw remover for it. Next the steering joint came loose before I had unscrewed the nut and the female torx fitting in the bolt went round so it all goes round and round. Ahhhh! I will try to unscrew the nut with a impact wrench or just cut through the nut with an angle grinder.
I haven't got the rotors delivered yet so I can't assemble the whole thing, but I test mounted the one caliper that was right and checked the clearance to the rim. About 7mm! I won't have to buy new rims. Great!

Finally I test mounted the rear disc brakes, stub axle, wheel hub and rotor on the car and it looks great! This is still with the wooden adapter mockup, I will try to find someone to machine me an adapter in steel next week. Get new break lines with rubber hoses next to the calipers and new handbrake cables and that should be it!

The rear disc brakes assembled. Note the old drum brakes to the left and the old drum on the floor!
