View Full Version : Blimey my Brakes are Brilliant!
I knew the pads on my curvy were getting low so I decided to put some new ones on. While I was at it I serviced the callipers - I had already done it at the end of last year but the pistons weren't sliding too smoothly & so I thought why not. Because I'd done it before it only took an afternoon & I did a way better job than last time.
The old pads had Tokico on the back so I'm wondering if they were the original ones? 10 years old??
The difference now with new Kyoto GG pads is incredible!! I'm quite pleased with myself & happy that every change I've made to my bike so far has just made it better & better :)
Just thought I'd share 'cos I'm quite chuffed. If you don't care heres a pic of a fish so your time wasn't wasted :nemo:
While I'm at it I may as well ask a question, This is a pic of the back pads last time I took them off. Is it normal for the disc to miss a bit??

Glad your brakes are working so well. I've always thought that the SV brakes, properly serviced and working as they should, are very good.
That ridge on the rear pad does suggest that the pad is overhanging the disc for some reason. They certainly shouldn't be like that if the pad is in the correct position. You may be well advised to have a good look at how the pads are sitting in the caliper and how they are aligned with the disc. There should be no friction material hanging over the edge of the disc.

Pads overlapping the disc is a HUGE no no!
The disc should ALWAYS over lap the pads by at least 1mm, think of the disaster that would occur if you're pulling on the lever or pushing the pedal and instead of the pads contacting the disc they're just pushing each other...
Get it looked at ASAP.
I assume you dont have the same issue with the front one?

Wow, that hadn't even occurred to me, very good point! I'll get them off tonight & see how the new ones fit compared to the current. This should be interesting, if the new ones are the same size then maybe the disc is smaller than it should be? It's the original disc though... hmmmm we'll see

No, front ones are lovely. Maybe I should have titled the thread 'My front brakes are Brilliant, the backs a mess!'

Its a curvy so IIRC its got the rear caliper hung under the swing arm as part of the rear wheel spacer and then supported by a strut to another part of the swinger.
I find it hard to think that any part of that could be the issue, I would ASSUME you've had the wrong size pad fitted previously but only because that makes "more" sense than the alternative (caliper or disc swap).

+1, and looking at the size of that ridge, that's exactly whats been happening.
Don't forget those front wheel bearings HoL, too much play on yours and need replacing. You should feel improvement form that too.

I've got the bearings at home, thats next on the list. It's just as well I love my bike, it needs it!
You've got me wondering now... If theres excessive play in the back wheel too then that could cause the pad to be too low as it seems to be. Onto the paddock stand when I get home!!

Na the spindle passes through the spacer tied to the rear caliper, you'd need a few other factors to go wrong before a dodgey bearing caused that.
Does the rear caliper also go on a slider on the inside of the swing arm, or is that just the pointy?
I don't know about a slider, it's attached by the torque arm & spacer hanger thing below

I guess I should do some work instead of over analysing it now, hopefully it should all become clear when I get home

Its been about 3 years since I've dismantled a curvy so my memory was a little hazey, that image brings it all back though. No it doesnt slide on the swing arm its just relys on the spindle, then those 2 bolt holes bolt direct to the caliper and then another mount on the caliper joins to the strut.
In which case no, you cant mount it wrong.
Do you have a pic of the caliper and can you measure your disc, we can at least then rule either of those 2 out.
I should point out I stole that photo from Smithy, mines nowhere near as clean as that. I'll measure etc when I get home later.
Well that explains that

Armstrong 230053, a quick search didn't tell me what bike they should be on but at least that was an easy fix :)

Not a problem, in honesty it's a good spot by you. There would be a lot of folk who wouldn't even question it.
Give your self a pat on the back, u just avoided at the very least soiling yourself.

Yep
Your right mate!
HoL want a tidied up hangar for the back? Still sitting in the shed (I think!)
Cheers Andy, but it'll just get as dirty as the one I've got now.
I hate bleeding brakes :( almost finished
