I’m looking for a set of aftermarket disc brakes. Mine are rusted.
Any problems to look out for with aftermarkets? How much is it to pay a garage to install them, and do they need to do any specific checks, or lining up the brakes, and adjusting it to the hoses?
Make sure you buy the decent quality discs from well-known manufacturers…Braking, Galfer, Brembo, EBC…don’t be tempted to buy the cheaper sh1t from China or Thailand or wherever else advertised on Ebay.
You gets what you pay for and where brakes are concerned why take a chance?
As far as fitting is concerned I would guess you aren’t looking at more than an hour’s labour, it isn’t a big job. As always I highly recommend Keith at Motopsycho (http://www.moto-psycho.co.uk/contact.html) in Kings Cross… he is a great mechanic, really nice bloke and very reasonable. Let him know I sent you if you choose to use him (Joel).
Good luck
But of course first we ask…why are you replacing rusted disks? Which bit is rusted?
All of it 
Waxy - is there any reason to choose one brand over another?
for the surface that meets the pads, drive down the road with the brake dragging - that’s that cleaned.
For the rest, tickle it with a wire brush then spray with VHT paint.
Not really…EBC and Brembo will tend to be more like OE replacements, whereas Braking and Galfer offer the wavy disc design, which is supposed to over some braking benefits over standard round discs.
Thanks Wavy.
I’m thinking I’ll go for the Braking discs.
Don’t know where that garage in Kings Cross is. It’s very stressful on the roads around there.
EBC and Brembo both offer wavy discs for most bikes I think. There is not really a huge difference in after market brands afaict though. Although they’ll all try and sell you their own fancy variation as the best thing ever to happen to brakes.
I have replacement EBC brakes on my Street because some yobs tried to hammer a disc lock off. They are easily equal to if not better than the OEM discs, and quite a bit lighter (also they are gold :D) if you care about that sort of thing.
Getting them fitted is pretty easy, any half decent garage should be able to do it for you. It’s a fairly simple job so I wouldn’t expect more than an hour or two of labour time at max. Stick it on a stand, take the front wheel off. Remove rotors. Put new rotors on. Put wheel back on. Check everything.
You will probably need replacement disc bolts to hold them on though. You aren’t meant to re-use them because of how tight they are I think. I got mine from www.probikekit.com.
Stressful? Don’t be such a big girls blouse!
What part of London woud you be coming from?
i like that no one has mentioned that he will need new pads with his discs… that will make the job longer, as to do a proper job, you need to clean the pistons before pushing them back into the calliper. depending how heavily rusted your original discs are, just holding the brake on for a bit wont fix things. it will remove light surface rust, but any more substantial deposits will end up leaving high-spots on your disc and you will end up with vibration under braking.
wave type discs offer less unsprung weight, (there for making your wheel lighter) also the wave style pattern gives the disc a larger surface area to in theory it should cool better and SHOULD be less prone to distortion. my own experience with wave style discs is that they give a slight ‘buzz’ through the bike when braking. had this on more than one bike with more than one type of wave discs. personally didnt like it, but never bothered the respective owners.
EBC discs (again, own experience) are pretty poor. all the ones i have had have ended up with vibration under braking (material transfer causing high spots) have warped, or have ended up with cracks.
the only brakes that i would recommended again, from personal experience, are either original equipment (unless its a suzuki as all their discs are ****) brembo, or grimeca (who make loads of OE brake discs for a good few bike manufacturers)
Thanks everyone.
try ABE in greenwich, they’ll make em while you wait etc, good quality too.
He aint doing it himself so explaining anything more than what garage to go to is a bit pointless anyways . I do not even see why he is bothering to look at discs if he getting the shop to do it . They will give him his choices and then shaft him for fitting something thats as simple as fitting a lightbulb .
Gee thanks.
Welll its true innit ? No offence ment or implied .
Maybe not, but the truth still hurts :ermm:
Surely the point of any question on here is to gain some more knowledge before going into the shop and trying to pick out if the shop is bullshiting… Matt gave his option and he detailed an answer so that the OP knows a bit more about the subject. Surely that’s a good thing?
For something like this I would head down to OMC and do it myself because then at least you will know what you have done is right and not half-arsed (trust me matt won’t let you get away with half-arsed things) so you then know that what you have on there is correctly done and exactly what YOU want…
