Garygazza Posted January 14, 2012 Share Posted January 14, 2012 My front caliper seals have started to leak brake fluid.On removal of the caliper piston it is very pitted and requires replacing.Are these calipers fitted to any other model .M and P list a kit for a 250 d and e,are they the same calipers?

Moderator mervin Posted January 14, 2012 Moderator Share Posted January 14, 2012 I would have thought a 78 bike would be an E model, yamaha designations for bikes started with A in 73 AFAIK , C would be 76 model. , and i seem to remember the XS250 being launched in 77 , anyway I think they where the same as the RD calipers of the day single piston swinging caliper Link to comment Share on other sites More sharing options...
Moderator drewpy Posted January 15, 2012 Moderator Share Posted January 15, 2012 '78 can be C or D, calipers you can use are some xs650's some Rd's xs400 sohc models except later ones xs750 and 850 xs 1100 Link to comment Share on other sites More sharing options...

Moderator mervin Posted January 18, 2012 Moderator Share Posted January 18, 2012 Drewps are the pistons the same as the E model RD,s ?? in which case RDBitz AKA Nick chambers on ebay does em and rhe seals and will be cheaper than the tired kraut i reckon merv http://stores.ebay.co.uk/RD-BITZ?_rdc=1 Link to comment Share on other sites More sharing options...
Moderator drewpy Posted January 18, 2012 Moderator Share Posted January 18, 2012 yea, I think it is the E model. I used the gear lever shaft from that model for my bike Link to comment Share on other sites More sharing options...
