Front brake performance poor & fluid spotted on caliper.

My front XT (m785) brake has been squealing like anything recently and I pretty much have no front brake.

Tried new pads which worked for a couple of weeks then same thing again.

Have now spotted there seems to be some fluid at the bottom of the caliper body (seems ok at banjo connection though).

I guess this means I have a leak, but is it possible to service/fix this or is a new caliper required?

    Calliper is non serviceable, so it's a new (any Shimano with the right hose attachment) one - unless the leak is at the banjo (a very light weep you may not see until it accumulates at the bottom to drop off?)

    Is it worth replacing the hose and banjo at the same time as replacing the caliper?

    No, not at all.
