Gonna do a complete brake rebuild soon. Have refurbed the master cylinder already. Pretty confident on the rest of it, do have 1 question though. When replacing the caliper seals, do they go in a particular way or can they go in either way round. Wasnt sure if they had a slight lip or not !!

The caliper Piston seals can go in either way round, they have a square cross-section. The dust seals on the caliper need restictiv position to seal for.

Warning (should it apply): I've had a number of bad experiences using bad K&L brake system parts, including caliper seals. I'd use OEM if at all possible.

I second that.
I have a couple of Z1B's restored, an '80 KZ1000LTD restored, a 1981 KZ550 restored and a 2008 KLR 650 for off road fun. My wife has a 2019 Suzuki DR 650 for on and off road.

Genuine factory parts are available and cheap. I don't see a ring listed anywhere. The part number at Scirocco’s post shows as the rubber piston seal at Partzilla.

There is indeed a steel ring that retains the dust seal on Z1 caliper bodies. Don't know about KZ1K's.

I replaced the dust seal some days ago.
The easiest way to install was to enter it on the piston first and then have it on the edge of the piston. Next was to turn the piston around to enter the opening of the calipper.

I had many attempt first by install the dust cover in the calipper and then install the piston, but I gave up :) the dust cover was always loosing from the calipper.

Good luck ! :)

When it comes to removing the piston, do I remove the boot first or pop the piston out first, then remove the boot ??
