Gents,
Started getting a long brake pedal travel yesterday, but haven't done any investigation as yet. Car still stops fine, and if you come off/on, you get a normal pedal again. Doesn't feel like a hydraulic problem, so I'm wondering if it's a warped disc / dodgy hub bearing pushing a piston back in. Anybody had anything similar?

Probably 'loose' wheel hub nut, l would jack up each corner starting with nearside rear and check for 'play'.
Hub nuts should be 270Nm.

Bracket/pivot above the brake pedal bent out of shape maybe?

Yup, it'll be a hub.

Yep, check all corners is a job for the morning.
Thanks all for a quick response as always.
I'll report back!

All,
Completely forgot to post the update.
Well, spot on diagnosis. Offside rear hub was a good half turn loose. Checked the rest, but they were all fine.
Hopefully no bearing damage, but I'll keep an eye on it over the next few weeks.

FYI - on my 400, all the hub nut positions are marked with paint, so it's easy to see whether there's been any movement. You only need to pop the centre cover out of the wheel to check, so well worth the effort. I've re marked mine.

Brakes fine again, but it's amazing how different the car feels generally.
Cheers,

I wish I had a pound for every time I've had to tighten up my rear nearside...

Replace the nut as soon as you can. Once loose they will keep on coming loose.

Correct. Its loose because its stretched. Every subsequent tightening will stretch it more.

are the nuts a standard Ford part?

Good question. Anyone know? They don't look it I have to admit.

Plans have some "improved" ones AFAIK - give them a ring.
