Will an R1 front master cylinder fit?

You could try a bolt and nut through the disconnected banjo end, with washers either side. You don't need the seal to be perfect, as long as it allows some pressure be developed for a second or so.

I took the caliper into work and got it off with an air line. Was really easy actually. I opened the bleed valve and put a tight bit of hose on it, pushed the other end on a air gun. Had to put a bolt in the banjo hole to block it and they popped out. Had a piece of wood where the brake disc would be so they came out level. Just need to press the sliding pin out on this one now.

Cheers guys I’ve done both calipers with new seals. Both calipers sliders were seized and it’s been a pain in the ass. Bikes all back together and system bled etc. Brake lever is nice and firm, but... when I push the bike I can hear the pads on the front disk. Is this normal? Doesn’t sound normal

[Chris_SVS]

Yes, they'll push back enough when the disc is rotating waay faster

[aesmith]

Normal if they're new pads, not really if you're refitting the existing one. However check again after a few miles before worrying. What I sometimes do is try to avoid using the front brake for a bit, then stop and check that the disks are cold. If you can't do that, check that they're the same temperature.

Oh that’s good to know. They are new pads. I got some ebc sintered HH pads. I am tempted to put the old ones back on though just to see the difference in what a reconditioned caliper with new HEL lines feels like. I’m being gentle on the new pads for a few hundred miles and I wouldn’t have to on the old pads. Plenty of life in them too

Perfectly normal for brakes new and old. When the brakes are on the pads are pushed against the disc, when off the pressure is released and the pads essentially stay where they are just about resting on the disc. That is where the noise is coming from. Lift the front end of the bike and spin the wheel, it should be free and easy and you will hear the noise of the pads on the disc. Now if its difficult to turn the wheel then you may have a brake related issue such as seized calipers etc, but considering what you've done I wouldn't think this will be the case.

Get used to the feel and feedback from the brake but there is no need to be gentle, just use them normally.

Two weeks later.... my brakes are brilliant. Thanks again guys

spot on
