R100S/6 Dual Disc Hydraulic Brakes / side car hydraulic steering damper

Worked on the R100s engine problem the other night...checked out coils, connections and had no luck. Decided to swap out the ignition condenser and sure enough that was the problem. engine fired right up and ran as it should.
Decided to dig into the front hydraulic brake system next. Tore down the master cylinder and disassembled it. did not look too significant internal rust. A new unit is available but at $400.00 I decided to rebuild mine...ordered a rebuild kit.
Had not been able to identify the manufacturer of the front disc brake calipers. Knew they were from an Asian bike cause they are "Tokico" units. Finally after looking at dozens of different calipers on EBay I found they are from a 1981 Suzuki GS750LX. Took mine apart and found that the pistons are rusted solid in the bores...not good. Attempted to find NOS calipers but none to be found...price lists showed them at nearly $200.00 each if they were available.

Went back to EBay and found a couple pairs for sale....ended up buying the set below for $55.00. Talked to the seller via phone and was assured they were rust free and usable as is...went ahead and ordered seal kits ($45.00) for them from another NOS parts supplier. I'll rebuild them upon receipt.

Been snooping around looking for a hydraulic steering damper. Found that many "sidecarists" use Mercedes Benz Bilstien units...and some use Volkswagen units. Looked over some photos of a Volkswagen unit on a sidecar and decided to go that route. Plus it was only $35.00 + shipping. Will need to fabricate a bracket of some sort but that won't be too difficult. So things are looking up and maybe we'll have a drivable sidecar soon.

Sold a pile of spare parts on EBay over the past 10 days....paid for all these new parts and have a couple hundred to spare.
