Any Hope experts?

OK. Did a ride yesterday and suffered brake failure.

I'd stored the bike upside down in the boot on the way and when I put it together the front brake was very spongy. A few pumps and it was better but clearly not well.

Half way round the ride it failed completely with no visible sign of leakage or break. I thought I must have caught a hose and pulled it loose enough to lose the fluid.

This morning I checked the hose bolts which seemed OK and opened the reservoir which is still full. Before I begin a full strip down at the weekend I wondered if anyone else has had similar. My current thinking is a seal has failed in the lever. It's a 4 pot caliper so if one had failed at that end I'd have expected either fluid leak or at least some braking.

Ideas anyone?

Email Hope and ask them......their customer and technical service is usually top notch.

if your brakes are like mine,(tech m4), there's a rubber diaphram in the top of the resovoir which can cause problems.
There are some instruction videos on hopes website which explain how to seat it properly.

My bikes been upside down a lot lately! It does weep oil from the resovoirs, touch wood, no problems yet...

edit;
ah, apparently the website has changed.
