Make sure your brake pins have antiseize compound!

Dropped the bike into a local tyre dealer to have a new set of boots, I decided at the same time to have the front pads replaced and left them to it whilst i grabbed a cuppa.

Came back to find out that they couldn't get a pin out of one of the calipers - so we tried to get it drilled out ....... Until the caliper cracked...

One trip to Bahnstormers later and £250 worse off...... Check them now!

If anyone wants it for parts - let me know, otherwise its going down the dump.

I've got a box full here, £75 each.


That's the first one of those type of calipers where i've ever seen the pin seized in place. Hence the box full of used ones.

Out of interest, how should you remove seized calliper pins from the later type of calliper design?

Pentratig oil other than that I'd go with a lot of heat and a punch. Wouldn't expect the seals to be upto much afterwards though if you've heated hell out of it.

I used a dremel with cutting disc to remove a section from the middle of the pin so the pads could be removed, then knocked the outer section through the caliper body with a pin punch and finally got some mole grips on the remaing section on the "blind" side to twist it out.
That was on my sons R1150R having suffered a winter of weekend commuting from S. Devon to S. wales.

There are two types of caliper pin on the later bmw caliper, one which never seizes ( the one in this post in my experiance) and other one with the chrome cover and the "push in" pin

A punch isn't much use on the later calipers as the pins don't go all the way through, they locate into a recess .
