Sanity check on front brakes please

Postby RichUK » Sun Oct 29, 2017 10:00 am

When I push my '08 990 around in the garage the front brakes make noise, a kind of hum or low pitch squeal.
Bike was recently washed and has only had a short ride since.

Is this normal or does it mean it's time for another caliper service?

I gave them a really good clean up at the start of the year (maybe 1,000 miles ago) but I'm thinking that wasn't a good enough clean, maybe the pistons now need to come out for a proper clean up?

Try freeing up the brake disc carrier bobbins first.

Just did that on my other bike but kind of thought that as the Brembo's are radial on the SD, thus are a fixed caliper with "floating" pistons, the disk would also be fixed and not floating?

Full/semi- floating afaik - bobbins should not be seized in position either way.

if you have track stands rear + front, does the front tyre spin freely when off the ground or do the brakes drag it to a stop?

I do have a stand that can lift either end but I've put off doing this job until next year now.

I'm putting the bike into makeshift dry storage for the winter as my garage starts to get damp with condensation around this time of year. Often the bike can be literally dripping water!
Once I pull her out of storage I'll lift the front, clear the bobbins and if necessary clean the pistons.

I have an 08 SD with 33,000 miles, which are all my miles except 666 miles. (Bought a new clock at rebuild, bike was totaled w/ less than 1K on clock.)

I live in Oregon and the bike does is not ridden in crap weather when they de-ice the roads.

A lot of Euro SD ridden in bad weather have had bad luck with the front brakes, to the point of locking up at speed.

Mine are still doing fine but not great as they were miles ago, but still in stock form as in never serviced.

This winter my bike will see a major walk thru the services.

Treat your front brakes with great care.
