hydraulic brake to buy

[SolemnWeasel]

Hello,

I am thinking to replace my leaking rear caliper (if I cannot fix it). Currently it is a Shimano BR-m525.
I am thinking to only replace the caliper and save money, and I don't want to spend much.
I could buy br-mt410 or mt200, just the caliper for about £14 with postage.

Question is - what should I buy - I think I can mix the old lever with a new caliper. I don't do any significant descents, so I guess 2 piston is enough.

Second question - what else do I need to buy - I guess the insert (barb) and olive - but the pictures of calipers I see don't show any bleeding port, is this something that needs to be added? Stupid question probably.

Thanks.

Get the right caliper and your existing hose/olive should just screw straight in. I did just this when my XT caliper started weeping on a piston. Replaced with the Deore M6000'ish version which was essentially the same thing except for some material/weight difference. Pistons were the same diameter but not ceramic in the lower spec component and also used the same pads. If they didn't have the logo on you wouldn't know the difference.

Can't comment on your set-up, but read up on the specs and you should be able to mix and match ok.

Factor in the hassle/expense of buying fluid and having to bleed the new system. Simple enough to do, but not everyone has the know how to do this and can really struggle....

Thanks, fortunately now I know how to bleed.
Question - so the old hose will just come out with the olive from the old caliper, no real need to replace them?

If it is a compression olive fitting, yes. However, some brakes use the banjo bolt fixing so you will need to match like for like

Most medium level Shimano ones have screws as per below. You unscrew the bolt (grey circled) and screw into the new caliper. You’ll lose some brake fluid in doing so, so will need to top it up.

You'll likely need to bleed the system as noted, in fact if there is a leak currently I'd do a full fluid replacement, you'll need to top it up anyway given that the new caliper won't have any fluid in it anyway. Doing a full bleed rather than a top up will ensure there are no contaminents elsewhere.

XT is banjo connector.

XT is banjo connector.

In which case, ignore what I said above.

Mine was the XT. OP is lower group level so may be screw fitting.
