Front pads

[Bat21]

Just done a front brake conversion to the 305mm discs, mine were the early 286mm.

I'm sure I read somewhere the 100 pads fit in the new callipers, they have slightly more surface area on them than the 80 pads.

Has anyone fitted 100 pads in theirs?

Yes.... run them for years....the only thing you might find is when new you have to leave out one of the anti squeal shims behind each pad as they are slightly thicker than 80 pads....once the pads have worn slightly you can refit.... ( although many 80's I've come across have long since had some if not all of the anti squeal shims lost .
Some of the aftermarket upgrade 100 series pads may be worth a try for extra performance ( EBC Greenstuff pads for instance )

When I had my 80 I use run 100 series pads, no issues

Sounds like they are thicker but have sane surface area.

 

[Bat21]

Thanks folks. Just checked and each pad is 3mm thicker.
Friction material is 11.4mm on the 100 pads and 10mm on the 80 pads.

So 15% more pad thickness and, as can be seen from the two images, a larger surface area too.

Where can I find the EBC Greenstuff pads Grimbo, RoughTrax don't seem to stock them.

Excellent Paul, will give those a go next time I need front pads.

EBC pads are probably best sourced direct.......
It mystifies me why they should not use as much friction material surface area as possible .... the 100 and 80 series metal backing plates are identical...
I have wondered before about 100 series calliper's on an 80 but never got any further than thinking .....

I have used the 100 series pads however the pedal needs to be pushed a little harder, it could be my own perception however, if you think of a blunt nail being pushed between the palms of your hands you get the idea. The extra friction from the additional surface area does not appear to counter the extra pressure needed to stop the vehicle?
