Bill_on_a_bike Posted June 22, 2009 Posted June 22, 2009 My back brake was squeeking horribley, So I thought i'd get the pads out to see if they're nackered. THey've got plenty of meat left on them so i think i'll just scuff them up and put some brake cleaner on them.My questions are:1. With regards copper grease, does it just go in a thin layer on the back of the pad?2. The pins i've removed look really rusty, and it's my understanding the brakes are supposed to slide along them freely. Should i try and scuff them back to better metal and should I then lightly grease them?thanksBill Quote
Pete Posted June 22, 2009 Posted June 22, 2009 There are a few things you can try, Bill. The first, like you said is to sand the top layer off to get them back to an even level, and that'll effectively give you another chance to bed them in. You could also try sanding a 45 degree angle on the leading edge of the pad to see if that makes a difference. And you're right about the copper slip on the back, the main area to pay attention to is where the piston(s) meets the back of the pads, as that's where the vibration happens. If the pins are rusty and all lumpy-like then you could try sanding them back to make them more smooth, or not bother and just buy some new ones - they're not too much (well, for a dealer anyway! I think mine were about 2 quid each!) Also check the anti-chatter shims if the brakes have any. Oh and what make are the pads? My rear ones are EBC HH Sintered and although they stop OK they squeek like bitches which is apparently a common problem. Sods. Quote
Bill_on_a_bike Posted June 22, 2009 Author Posted June 22, 2009 They're EBC something or others, the model numbers been rubbed off by the piston. I've just realised i've only got 1 shim! I guess I should replace this at some point. There's been no lack in performance from the brakes atall, they stop me right up and they'll lock the wheel if I push them hard, just they squeek like mad-not cool.Cheers pete i'll give the pins a scratch and see how they come up.

kja.busa Posted June 22, 2009 Posted June 22, 2009 I'm sure I've seen someone on ebay making stainless steel pins to replace the rotting originals. Does your bike have braided hoses fitted? If you feel the brakes are somewhat lacking they are a good investment, and don't cost the earth. Quote
Bill_on_a_bike Posted June 22, 2009 Author Posted June 22, 2009 Cheers kja. I've heard nothing but good things about braided hoses, bar the extra cost on rubbers. I might consider it if i'm ever trying to up the braking power.Just want to stop the buggers squeeking. Quote
kja.busa Posted June 22, 2009 Posted June 22, 2009 The original rubber hoses are only meant to last a few years and are recommended to be replaced every few years by the manufacturers. Regarding the squealing I would fit the shims, the pads could be old and have glazed too, once they glaze the heat build causes the pad to go hard, which compounds the problem. Personally if the problem persists I'd change them for genuine Suzuki pads, I've just recently gone back to them myself, and I'm impressed with their performance, they seem to be making a real effort to try and stop people using aftermarket pads.

Bill_on_a_bike Posted June 22, 2009 Author Posted June 22, 2009 Cheers kja. I will do if this doesn't work, at very least i need to get a second shim. I just can't find my copper grease, the damn stuff's always there when you're looking for anything else.Refit and short ride to see what's what. Quote
kja.busa Posted June 22, 2009 Posted June 22, 2009 Don't over do the copper grease it can cause the piston seals to rot, red rubber grease is better. Quote
