So while waiting for parts to return from powder coating,I turned my attention to the front brake caliper which didn't come on the bike but I want to try return to its original disc and caliper. I've managed to strip it down to the piston,But this is the problem the piston is in the fully returned position as per pics. So options are compressed air to force it out ? Persist with trying to force it out ? Or are there any other methods? I don't have the master cylinder.
Compressed air can be a bit savage at times, try connecting a grease gun and see if you can pump the piston out that way
I always use an airline, just be careful which way you point the piston when you do it! I had an almost identical caliper on my z400 and they are terrifyingly bad even when rebuilt, Braking was just a suggestion
There is nothing like a 2 stroke ! I own a 2 stroke car.....844cc 3 cylinder FWD. A car like this won the RAC rally in 1961 and 1962. Just drive it like you stole it lol ( like all 2 strokes )
Simplest solution after an air line, is piston pliers. Something like this, https://www.amazon.co.uk/Sealey-VS1806-Motorcycle-Piston-Removal/dp/B000WZJ7NO. Andy
So with been a thrifty tight Yorkshire man not wanting to spend money on a tool I'll only use a couple of times maybe? I did some research and came up with this solution a socket/Alan key affair and after a little heat and some expletives we had a winner..
I was going to suggest the grease gun method, as someone has already suggested. It NEVER fails & more importantly is safe, unlike compressed air !! But I see you've had success ! Yes, people will have had success with compressed air, but without care this method can prove very dangerous. I know, I've managed to get a caliper jammed on my fingers to the point that in extreme pain, I really was contemplating going to hospital for help !! I did manage to get it off, but it did hurt !! After that I made an adaptor that I can screw into a caliper, with a grease nipple on. Screw it into the caliper, plug on the grease gun & pump. Never fails
Collected my powder coated frame and parts today now the fun begins rebuilding the Rd200..really impressed with the quality of the finish
After a little research I've decided to build myself a little blaster box will post some pics up of before and after blasting once all the parts arrive
First attempt at blasting before and after pics just a little tweaking with access and the nozzle blocking
