 |

Hi,
Just a quick question.
What is the difference between 'Standard' and 'Sintered' brake pads?
Thanks  ____________________ Like a Yorkie - I'm not for the girls  |

I'm not exactly sure how Standard pads are made, other than pressing?
Sintered pads are somewhat porous though, as they're made of a big pile of semi-metallic powder plus whatever else goes in (a very odd mixture of things, mainly chalk), put in a press and heated until they almost melt. The powder granules stick together without becoming molten. I imagine their coefficient of friction is higher and that they will clean themselves better perhaps.
Basically, like Keith says, it's primarily a difference in composition (and manufacture) to improve their friction qualities. I'm not sure if they wear faster, but probably.

I believe that over time, sintered pads will eat your brake discs faster than standard pads, but it's a small price for better braking innit.  |

The difference you need to know about is that sintered brake pads have more friction over a greater range of temperatures whereas standard pads can go 'off' if they get too hot. They have higher friction and so are more efficient at slowing you down, the downside of this is that they will wear your discs out more quickly.
Having a lot of metal in them means the pads themselves actually last quite a long time.
Another plus point of sintered pads is that they are unaffected by water on the disc/pads.
To summarise, sintered pads are better but wear your disc out more quickly. Check out the price of pattern discs before you decide to use them. ____________________ “Rule one: Always stick around for one more drink. That's when things happen. That's when you find out everything you want to know.”

Wow! Plenty of responses... Thanks guys. Think I'm going to stick to standard pads this time round. My damn brakes have decided to go through a 'binding' phase. Due for their annual rebuild I think.
Thanks again.  ____________________ Like a Yorkie - I'm not for the girls  |

Just had a thought... Would it be possible for braided aftermarket lines to be cheaper than replacement OE rubber ones?
It certainly looks like it, as OE brake lines for an NT650 are 40 odd dollars on a site which I finally managed to find to give a price for rubber lines. $40 for rubber ones, vs. $20-25 for braided?  ____________________ I must not be a troll...

hi ya peeps,
Thanks for the advice so far, it's been a great help. I do however, have a few more questions.
My friend and I took a look at my caliper the other day, to try and find out why it was binding so much. We did not have the whole thing apart, but from where we could see, the pistons were not sticking and it seemed to be 'floating' OK(ish).
When I brake I get a noise that would indicate that the pads or disc are rubbing uneven. The noise comes and goes in a rhythmic fashion and looking at one of my pads, its down to the wear marker on one side, but plenty of material left on the other.
I'm hoping that I'm just wrong about it floating properly. My local bike mechanic has said he'd take a look, but has suggested new pistons and seals. Do you think it's also worthwhile replacing the disc? This binding problem has made the surface quite uneven.
Think I'll refer to Korn's guide too, save myselfa few bob. I like getting my hands mucky.
Thanks again.
