Ok boys we need help .... does anyone have tucked in their garage seals for master cylinder for back brakes to fit a lovely GS850 The old girl (the bike not Mrs JMK ) passed her wof today but they mentioned brakes would need doing in near future, riding back to work the brakes decided they were going to fail today not the near future!!! So at the moment the JMK's will not be riding Sunday Havent tried to get the seals from Boyds yet ... tomorrows job
what failed? Are they just not working or is oil leaking?
You can see air coming out master cylinder when you pump brake
I usually go straight to a brake specialist like Auto Stop and take Vern the vernier and the seals with me. Genuine part prices suck... except for Guzzis, they is cheap as chips
Sorry jmk, no spare MC or piston seals. Do have a spare MC and caliper, though it would be unlikely that they would be much good without a full strip and re-build as they have been hanging around (literally) dripping fluid for at least a couple of years and look remarkably unloved.
Oh yeah, I can bring a working Brembo M/c for 7/8 bars- have it fitted and blead in 15 mins in the carpark if it gets that desperate that you can't come on the ride If the warning switch fittings are not compatable just tap the back brake when your stopping Mmmm Brembo , you won't know yourself.. probably end up buying a Ducati http://www.trademe.co.nz/Browse/List...x?id=247634130
Back brake MC. But you is right. I can bring my spare down and chuck it in... worth a try.
Oh back brake, I see it now Can't help with that sorry Still think ya should buy a Ducati
like croc, i have the whole rear mc of unknown condition if you want to swap 'em. but probably best to fit new seals asap.
Strip your m/c and caliper. Spares that have sat in garages for yonks will be full of crap. Clean yours up, but you'll probably find the ali bore pitted. If the pitting is too severe, you'll need to buy a new m/c. If pitting is minor, new seals will work.
Your right Dodgy not cheap like Brembo seals kits. Brand new rear slave cylinder kit for 1981 Kat is about $73.00 & front slave cylinder kit is about $132.00. Both in NZ Suzuki stock and will be here tomorrow
Seedy Katzales 1981 Kat is about $73.00 & front slave cylinder kit is about $132.00. Holy crap Katman! Your right, the Guzzi front and rear was less than $20 including freight... Weird that a Mk1 was nearly double the price of a GS850 new and the parts are probably half or less the price, you Jap classic chaps sure are dedicated (much respect), I would spew at the cost of some of the NOS or repro stock exhausts for late 70's early 80's Japanese machines.
Have stripped it and ... bore doesnt seem to be pitted and going to attempt to buy kit/seals tomorrow and clean the master cylinder Suppose at least it has a warrant
After cleaning up master cylinder it is quite badly pitted!!! So we waiting for some prices to replace it
Who do you Auckland boys deal with, Boyds dont have one in stock and talking of getting one in from Japan (price dependent on our part of course!!
