Thread: Disco front brake calipers

I rebuilt mine a while ago and I read comments on the forum saying it would be difficult to get the two half to seal again. So I did mine without separating them. A bit fiddly, but completely doable. Finding something flat to help drive the steel retainer in square was the key.

P.s. Don't throw away the old bits until you're complete. Worst case you wreck one of the steel retainers, you can reuse one of the old ones.

Have your seal kits got the Channel seals in them? If so there's no great mystry to splitting them. And yes the dust seal retainers are a main in the arse

Thanks for the info Guys,
The seal kit and pistons have just arrived and no they didn't include channel seals - I ordered a spare seal kit for $10 just in case I wrecked some installing them.
I will have a go without splitting them - are they a standard round seal between the halves? as I have both metric and imp seal kits here.

Nomally there just a round flat oring type seal
