New front brakes --> new brake pads?

[DanOz]

Hi guys,
I've bought these front disks for my triple

the disks are specific for Speed Triple so in theory I shouldn't need any spaciers or whatever, but my question is

shall I replace the brake pads as well?
The discs are rated as "racing discs" , but at the end of the day are steel discs, so I'm not sure what the racing refers to.
I'm not expecting the bike to brake better or whatever, is for pure bling reasons.
The current pads, that came with the bike, have slightly more than 4000 Kms on, so they should be in reasonable good conditions.

So, shall I change the pads as well when I put the new disks on?

nah leave them in mate, theres no point in thowing away perfectly good brake pads!

P.S. Fuckin Sweet dude!

[Cleverlie]

Yeah i reckon change the pads aswell.
Racing could just mean it weighs less? :confused1:

Edit: Well you could keep em but i'd go with let them all wear in together and get all the grooves the same.

look the goods

Yeah..fresh discs, fresh pads....:ayyy:

[DanOz]

Ok it sounds to me that ideally I should change pads, but if I don't, it shouldn't be too bad either, just that the new discs might end up being not too happy about it..... that's all. Right?

I mean, it is not that the "original" pads won't work properly on these sort of discs
you know...... if I would have to pick a sigle part on the bike I don't want problems with, the choice would go on the brakes.... :mod_smilie_rockwoot

[lilninja]

mate the discs dont know if they are being clamped on by new pads?
and the question is are you just gonna stick the same type of pad in cause if so then there is no point in replacing them!
Depends how much $$$ you have to throw around I guess!

Here I go again being different :beer:

The standard pads are fine & will probably be better for your new rotors than brand new race pads.
Why you ask, well let me explain:
OEM pads are always softer than after market pads because the factory doesn't want unwarranted warranty claims of warped rotors & new rotors will bed in better with a softer pad first set.

The only reason you wouldn't use old pads is if major uneven wear (one end is thicker than the other) or there damaged in which case there is a major problem with your calipers for that to happen, just use some sand paper laid out on a flat surface & scuff up the faces before using on your new rotors & they will be same as using new ones.

It is total BS you need new pads with new rotors because what happens when those pads wear out & you can't buy the exact same brake pad again, you going to change your rotors.

[Pokey]

Only reason you'd need to change is cause the pads are grooved the same as the old discs, so when you put them on the new discs they'll cut the same grooves in them
If your old discs are still pretty good it shouldn't be a problem

Nice bling :ayyy:

Mate I agree, no need to put new pads in if they are in good nick.
Remember though that these new discs could be softer than standard and using HH pads or even standard pads on them could wear them out quicker.
In my experience the standard factory pads are the hardest and often last the longest. Shit pads though.

Clean them up on some sandpaper and a flat surface and put them in. Then when they wear out, do some experimenting on which pads work best.

New disc new pads

When changing disc you should always change pads there are several reasons for this
For a start worn in pads have lost the bedding in properties as they have been heat cycled , there is a lot of new pads coming out these days coated in titanium to help speed up the bedding in time
Also you need the pads to be flat otherwise you are going to have uneven wear on your new disc to start off with, and getting them flat on some sandpaper on the bench aren’t the easiest of things

you need to also check what type of pad material the disc are rated for not all disc can use the same materials

hope this helps some what

Racing could refer to a few things, Are they stainless or cast iron. If they are cast then new brake pads to suit would be required.
If it means, as stated above that they are just a little thinner to save weight or it could mean nothing and is a marketing thing.
Some OEM pads are good but there is always something better. Did you know that Suzuki superbike team use Std Suzi pads. Again more of a marketing thing than what is the best.

hi danoz i worked for bendix brakes in sydney for a few years,not to say i'm an expert but do know a little about linings and the such.unless the pads have really uneven wear because of caliper problems ,there is no reason why you need to change pads.haveing said that if i put new rotors on a bike or car, new pads are a given.you have spent some money on rotors why not complete the process.brake pad material is the same all the way through,the material is made up in a mix then bonded on to a backing plate or shoe.i know this is a bit off field but we used to supply state rail with shoes for trains and if they replace a wheel a new set of linings go with it.

The pad is much softer than the disk, so the pad will wear to the shape of the disk, rather than the disk taking the shape of the pad. But it will take a while for the groves in the pad to be flattened and until that happens, you have less brakes.
Theres also a chance that the grooves in the pad may cause localized hot spots which may lead to dishing/warping of the disks but thats a very small possibility.
Personally, I'd buy new pads as well.
