Brake Pad wear (how much pad is there?)
« on: February 20, 2015, 12:46:32 pm »
Since I have done the majority of my miles in the crud and salt that they spread on the roads, i though i would strip down the brakes and give them a good clean as they were sticking a little, and i wanted to get my grease on the bolts and pins.

What are your rear pads like...I reckon there is only about 2mm left (only done 4k miles).  Are these like the RT pads with barely any pads to start with?
I know that I am heavy on my rear as do a lot of slow riding in town ......the front pads are all about double the thickness.

Glad i did it though as they were really dirty and clogged up.  Now good as new.

I had to do it regularly on the old Sprint to the point that one time i had to replace the pistons.  Bit costly, hence i thought i should start as i meant to go on with a full clean out.
Took about hour to do all round.

On the EBC Brakes Direct web site
it gives the dimensions of the two rear pads as being 96.7 x 42 x 9.7mm and 77.3 x 42 x 8mm.

I think those last figures ( 9.7mm and 8mm ) are the overall thickness of the pads when new.

From Page 129 of the Owners Handbook...
The Minimum thickness line is the bottom of the "Grooves" which is 1.5mm (0.06 in) from the backing plate.
If you can't see the grooves then the pads need to be replaced asap

To illustrate what Gordon said, attached is the relevant section from the service manual.

I just got lucky.  Not sure I could do it again.

The rear pads start out close to the same thickness as the front pads. My rears were done at 57,000kms. I replaced the fronts at the same time with Ferodos. Compared with the ST1100, the rear pads don't have near as much material on them. The brakes work a lot better though!
