The place to come to share your technical expertise, or just find out what the little springy thing is that's just pinged out of sight under the work-bench.
Hi all, have a 1990 Exup, with blue spots and goodridge hoses, but orginal master cylinder, brakes work"ok" but take some pulling, and certainly wouldn't do a "stoppie". Having spoken to people, and read a post on here about the disc bobbins l checked mine, l can turn them all with pliars, but cant feel any real side movement of the disc, just before l buy the R1 caliper, would the bobbins being tight affect the braking performance, there is no judderingeven under heavy braking, thanks..
If the bobbins aren't silly loose then they'll just be keeping the rotor on centre to its natural track
I'd say the poor performance would be down to the master cylinder being mismatched. It'll make a huge difference changing it
Cheers Stig, let the search begin, l managed to get my Exup valve sorted by the way, had a new outer bush made, much quiter now!! Will let you know how l get on with the brakes, thanks again to all.
Hi, just an update on my front brake issues, well how right were you guys, thanks Stig, Nuggett, and Jay, got a mint Thunder Ace master cylinder off ebay, did the fork oil seals at the same time, and the brakes are now transformed, cannot believe the difference, big, big thanks to you all, bike is now ready for going to the Classic TT in August!!
