I went to ride my wife's bike to check I'd indexed her gears properly and the front brake doesn't work! I've never bled or touched a disk brake for maintenance before.
It's a Mono M4 as in pic below. There seems to be some fluid around the reservoir cap seal on the lever. Squeezing the lever makes the pads move a little, but not enough to stop the wheel whatsoever.
Does anyone have a link to a good guide? I don't have a bleed kit either. I do have a syringe and there are loads of motorbike shops around where I'm sure I can buy some DOT 5.1. Can I remove the reservoir cap, pour in a little fluid, put the cap back on and see what happens?
I've been in Thailand for a week and although I did bring spares, disk brake seals weren't among them. For the leak to have occurred, is the seal likely to be broken? It'll cost me £10 in postage from CRC. If needs be though, is this what I'm after?
Thanks a lot,
