Re: Very weak rear brake?!
Here's a thought - if it's no good from standard, even when rebuilt, why not modify it so it is good?
On the Triumph T595 the standard mod was to replace the 14mm rear master with a 1/2" rear master off a kawaksaki ZXR400L / ZXR750. This made the brake require much less pedal input and gave modulation instead of on/off. You could also modify the pivot for the cleat so that your foot had more leverage over the master cylinder.
Don't struggle with rubbish, mod until it works

Re: Very weak rear brake?!
Thats gas how a bike can dictate your riding style, my first bike was so bad i pretty much used the front brake, and then used the back brake as the horn because the horn wasnt as loud as the oul dodgy drumCRM wrote:Yep, pretty well, when i grew up i was always taught to use 75/25 on the brakes. bear in mind 350lc's had shit front brakes, and the rears were hardly much better. you did longer skids in your undies back then.davedrave wrote:Just curious what has being 40 odd to do with using the back brake?CRM wrote:self answered your own question there.
my UK bike has an awsome rear brake (being 40 odd i use the rear brake alot) however i have owned many a NC30 which had crap rear brakes.
new disk will help, however fresh pads, and rebuild the caliper and fresh fluid will ensure it works correctly.
moving on 20 years brakes are superb, ok the NC30 and RC30 were same era, but i couldnt afford one then like most. however i think it's an age thing, i use the rear alot in town and at slower speeds, makes the bike a bit more controllable. besides 15 stone doesnt help and i am too fat and lazy to be giving it a handful of front brake and getting all uncomfortable.

Re: Very weak rear brake?!
Just wanted to say thanks to everyone again for their input :)
I plan on replacing the disc, and doing a full overhaul on the rear brake system
Oh one other thing!... When i purchase a new back disc, which would you guys recommend?
Sourced the original part from David Silver for £79 and the EBC part from Rick O is £100.
Is the EBC worth the cost?
Thanks again!
Wes

Re: Very weak rear brake?!
Speak with Rick, think he does a selection of aftermarket discs which are of good value and perform well. You can get a good enough rear disc for sub £50.

Re: Very weak rear brake?!
I often only use the rear brake when slowing down gently. Like coming up to a roundabout i brake early with the rear and only use the front if i know im going to have to stop.
The other week this failed as i hit the rear in the wet and the bike snapped sideways. Managed to get it under control and stop for the roundabout without getting squashed by the large SUV going through. Not sure if it was the shinko on the back or painted lines on the road. Probably both!
But the rear brake is a lot weaker than on my GPX 250.

Re: Very weak rear brake?!
Hey all,
Just wanted to tell everyone that i've just gotten off the phone with Rick and he's an absolute gem of a guy! Really so helpful and a wealth of knowledge. It makes me really want to meet more people from 400GB!
Had a nice long chat with him and i've been advised to clean out the caliper and check for seized pistons and gunge build up under the dust seals... change fluid and see how it goes from there. Would probably find out loads more just by opening them up :)
Also going to be looking at changing the shock
Cheers again everyone and indeed Mr. Oliver!

Re: Very weak rear brake?!
I hardly ever touch my rear brake, mainly because it hardly works - it's on my list of shit I have to deal with.
NC30's eh?

Hey iDemonix, your bike looks exactly the same as mine...
