Decided it would be a good idea to pull of my front calipers today, to check my front pads. Ever since I fitted them, they have made a wierd scraping noise.

I'm glad I checked them, they are almost down to the metal!!

The bloody things are not even 3 months old, and I would take a guess that they've seen less than 1500km's!

This will be the first and last time I buy SBS HH pads.

i wouldnt be buying sbs hh pads if i wanted them to last, thats what i use to race with but they give good stopping power and really nice feel to em, if your going to grab a huge fistfull of front stoppers there pretty good,
when changing your pads be sure to lightly sand your front disks as well, does help
cheers

I'd better keep an eye on my EBC HH pads then.. *checks*

They have the same feel on the brake level now as my last set of pads which were shagged... but my brake fluid is black as.. Better flush it out soon..

Try EBC's Jase.. They performed well at PI, and are good on the street..

flushing brake fluid, ugh im not looking forward to doing that on my bike. I've just heard of a lot of problems that people have had with multipot front calipers.

Not sure what my brakes are like either *ponders*

the calipers on the GPx are among the easy ones to flush and bleed
you can do this as a one person operation
(I did it myself b4 the PI Track Day)
some tricks...
for the fronts, make sure the master cylinder is level..tilt the bars until so
and then make sure, the level does not fall too far, as you bleed/flush 'em
then (with a piece of clear tube into a container)
as you squeeze the lever, slowly open the bleed nipple
some resistance should be felt as you squeeze the lever
and the fluid comes out the bleed nipple (probably black and with bubbles in it )
it is a bit of a black art, but you will get the hang of it
the multipot caliper on the GPx is not a problem
as the bleed nipple is at the the top of the caliper, away from the hose

hth

cheers

flushing brake fluid is easy, dont listen to the urban myths its not rocket science.
For the front bleed one side at a time, do what smitty says above, take your time and use new fluid.
If at the end of the procedure you still have a soft brake lever as is the main problem ppl suffer all you do is park your bike overnight, pullin the brake lever and leave it. The reason for soft lever is bubble by leaving the brake lever open all night it brings all the bubble to the highest point. The next day top up brake fluid and your done.

I'm about to strip down the front and rear brakes on my GPX might make a power point show on how to do it.

Cheers for the responses.

I've done brake bleeding before. For some reason I was just concerned that it might have been a bit of a fiddly thing to do on the gpx as i've heard of others having problems with getting the bleeding right on multi pot calipered bikes in the past. my only experiences in the past being with single pot single disc brakes.

I guess on my day off i'll go to the auto shop and get some dot4 fluid (yeah i know about the water absorbing properties & the big no no on using "unknown" fluid and to not do the change in high humidity/rain, etc...

I bleed mine after every couple of outings but the best thing I did recently was to strip the calipers and give them a good clean up. The brake feel improved 50%, I also changed to dot 5.1 fluid but I wouldn't think that would be necessary for the street.
I'm currently using Gold Fren Carbon s3 racing brake pads. At $30 a pair ($60 for the fronts) you can't beat em, although for the street I'd say the cheaper sintered pads would be fine..
White racing in Sydney sell em, they are also selling Putoline, full synthetic oil for $35 for 4 litres...

Ordered a set of EBC sintereds... they have to be better than those bloody SBS HH's!

well the sintered SBS pads on the GPx work just fine
at 60kmh and......230kmh
and don't wear out in 1500km.....
10,000 coming up (and they will need doing)

jase, ive run both & found em both ok..tho i think the EBC squeel like a bitch occasionally from memory....pull up ok tho..
