Hi Rob, Many thanks for confirming the conclusions I was beginning to arrive at and for the names of possible brake system manufacturers. The US bike market being an explanation for the imperial dimension now makes perfect sense. I'm sure that these master cylinders are from a road bike; as well as ...

Well, the overhaul kits that I have bought on eBay, based on a photograph of the contents, are for a Honda MBX50 but, according to the seller, exactly the same kit fits a large number of different Honda models. Only when the kits arrive will I know if they are absolutely the correct ones for my part...

Gents, I can't thank you enough for your excellent advice; you have successfully solved the problem for me. Following up your suggestions that it looks like a Honda part and having now removed the innards from the master cylinder, I have found advertisements on eBay for Honda master cylinder repair ...

Hi, Here are some pictures of one of a pair of heel brake master cylinders fitted to a mid-1970's Evans VP-1. Can anyone identify its origins (motor bike, perhaps)? It bears no maker's name, just instructions on the reservoir lid (in both English and French) to use Dot 3 brake fluid. I need to locat...

Has anyone got a small piece of 2024-T3 (or equivalent - the US plans say 24ST) that they would be prepared to part with for a suitable consideration? I need two short lengths 3/16" thick by 1" wide by 5" long, or a larger piece from which I could cut them. They are for use as 'radius blocks' in bet...

Many thanks to both cardiffrob and G-SIPA for their help and suggestions - apologies for this late acknowledgement but I managed somehow to lock myself out of the Forum!

John.

Hi, Can anyone please help with some second hand, lightweight 5" wheels, axles and hydraulic brakes to replace the heavy and clapped out Beagle Pup ones on my VP-1? If not, any suggestions as to where best to buy something new? Matco in the US is the only source that I have found so far. Many thanks...

Just to put this topic to bed, Dunlop Aerospace (now Meggitt Aircraft Braking Systems) could not have been more helpful and managed to produce the original drawings from the late 60s. Among other things, this information confirms that the O rings I sourced based on SteveB's advice should do the job ...

Again, many thanks for all this advice. From all these excellent leads, I am sure that I shall be able to solve the problem. Worst case, Dunlop Aerospace have confirmed that they still have the drawings and are looking to see if they can release them to me. Incidentally, my first car was a Morris 8 ...

Gents, thank you very much indeed for all this most helpful advice. I have now got the calipers in pieces and, apart from the rubbers, I reckon they are in reasonable shape for their age - there's just one bit of corrosion on one of the ali pistons, fortunately away from the seal area. The pistons d...

Steve, That's really helpful, thank you very much indeed. I haven't yet popped a piston because I might have difficulty getting it back and I need it in place to help me apply air/hydraulic pressure to shift its seized mate - if you see what I mean. As soon as I have removed a piston, I shall indeed...

I have an early Evans VP-1 fitted with Dunlop brake calipers dated 1969, Part No H52730, using Lockheed brake fluid. The rectangular (hydraulic) portion of the caliper measures approximately 11cm x 4.5cm x 2cm with 2 circular pistons with attached friction material, each 3cm in diameter. The non-mov...
