Default Disc brake

Hi I have a disc brake on my mountain bike , it works but
not as well as it should work in my opinion, Ive taking out
the pads and sanded the top of them any access oil and dirt,
and then put it back on again. They were the same , can
anyone give me any advice what to clean or do with them and
the disc to make them work any better.

Thanks alot .

1. What make and model disc brake? There are many and
either hydraulic or mechanical.

2. When you pull the brake lever, do you touch your bar?

3. You only have "a brake"? Do you have a different type of
brake in the front and rear?

4. Did you clean the rotor as well as the pads?

5. Did you accidentally spill lube on the pads?

6. How old are the pads?

Need more info. What brand? Are your brake pads broken in?
Did the brakes work better before? Was your pads
contaminated with oil?

I've never cleaned my pads or rotors. I only had to replace
the pads as they wore out and only dealth with loss of power
as the new pads were being broken in.

All I can say the disc gets very warm because its not
actualy stopping you , you have to sorta hold it in and it
dosent actually stop you completly but just enough to get
round the corner, or use your feet stopping. So it isnt
gripping the disc properly ?

The rotor is the disc itself.

That's the answer then. The pads are ruined (sanded or not)
so need replacing. The disc itself will also be
contaminated, so will need cleaning thoroughly before you
introduce the new pads. Use soapy water followed by rubbing
alcohol to clean the disc.

The new pads will need breaking in for a few hours before
the performance comes in full.

Two years off one set of pads isn't too bad anyway... don't
feel bad about having to replace them.

Be sure to protect the brakes from grease and oil next time.

Ahh cheers never thought getting oil near them would be that bad , just a
matter of sanding it over the pad and it would work again . What price would
u think it will cost for a decent pair of pads.

You need to get pads for the model of you disc brakes.
Pads are specific to the manufacturer and run from
US$12 to US$25.

Before you buy new ones, place your old ones on the stove
(the metal-coil range is good) until the oil in the pad
burns off. It should work as good as new.

I did this on my grease-contaminated pads and now they're on
the too-strong side...

Looks as though you might be in the UK (ntlworld). Take a
look at chain reaction to get an idea of replacement pad
prices, you won't find them much cheaper elsewhere.

<http://www.chainreactioncycles.com/...s.asp?category-
=Brake+Pads&thumb nails=true>

You'll need to look for an exact make/model match to the
disc brakes on your bike (or at least the Fibrax equivelent
copy; few £ cheaper). If in doubt take the bike down to a
shop and ask for advice.

I think you'll find the pad swap simple, it will take longer
to give that rotor a good clean!

Try squirting water on the pads while ridin.. its not as
hard as it sounds and use alot of water to break them
in.. it works

(People here prefer you answer below the text you quote, or
answer below each point you are tackling, by the way - just
trying to help!)

',;~}~

OK, you *MAY* not need new pads - as someone else said,
scrub the rotor (disc) real clean - wire wool or a green
scrubbing pad and dishwashing liquid work well for me.

Next, you can heat those pads up some, which will burn most
of the oil off/out - don't go too hot, though, or you may
break the bond between metal and friction material. Just
heat 'em until they start smoking a little.

Next, put it all back together, and smear the disc with wet
mud - fine, silty mud with no big stones. Now, ride and
brake - repeat until performance is returned.

The mud helps bed things all back in again, and also helps
draw out any remaining oily crap from the pads.

Hope that helps!

Ah, I think we've found your problem.

The problem you have is that you have crap brakes. No amount
of baking, rubbing mud on them or divine brake dancing will
make them work well.

Default Re: Disc brake

Just to add my two pence of advice...

Everyone says "don't get oil on the pads and rotor". In my
experience, this has to be taken to the extreme. Even a
finger print on the pad will noticably decrease breaking
performance. Keep the pads and rotor absolutely oil-less.

And be careful with that "disc brake cleaner" fluid you get
from bike shops. Some disc breaks (like my Hayes HMX-1
mechs) will actually be damaged by the "disc brake cleaner"
- on the HMX-1s you have to use a special alcohol spray that
you can buy from electronics shops like Maplin.

Thanks, Jack
