Brake pad replacement (servo brakes)

[k12pfc]

Do I need to be extra careful/do anything different to a normal braking system, when changing the brake pads on a 2006 1200gs with servo brakes. Everything works fine but I need to change brake pads soon. Surely I can't f@*k the servo unit up just by changing the pads...can I?

Personally? While you are doing it I would change all the brake fluids ESPECIALLY if you have no history of it being done?

BUT Do it before you change the pads so that you are not pushing "dirty" fluid back through the Unit!

I think you need a special 'tool' to flush the system if its servo assisted? Anyone know?

Very simple easy job. Just remember when replacing the front pads operate the brake lever after change one set of pads before you start on the pads on the other side other.

If you don't you'll lose brake fluid out of the servo/abs modulator overflow. then when you operate the brake lever the level could be low in the modulator reservoirs.

No, Not really, You just need to make sure you do NOT allow the servo unit to run dry of fluid!

Just don't push the pistons back too hard.

I have non servo ABS but I believe brakes are the same on servo models. I had three out of four pistons seized and had to be pushed out with the hydraulics. Strange because pad wear was only slightly uneven.

The seals were ok but the seal grooves needed a good clean. Red rubber grease on rebuild & job's a goodun.
If the pistons are pitted BMW sell calliper rebuild kits at about £60 per calliper.

You will need a stent funnel for the servo or if you are fairly handy you can make one.

There are tutorials on Youtube like this one https://www.youtube.com/watch?v=YLM25NYvlas no commentary just weird funky music.

If your fairly competent with mechanics its reasonably straightforward job does take time as the fuel tank has to come off so strip down of panels.

I use a cordless drill with torx attachment when I take the panels off it speeds up the process.

Looking at that its little wonder that the top of the engine suffers from corrosion on these bikes if his standard of cleanliness is the same across BM stealers or any others working on them. I would have expected to see lots and lots brake cleaner used to clean off all that spilled DOT4
