Brake problem

Repoman · Oct 16, 2018

Morning
Driving to work in my 92 Defender 90 this morning and I had to slam the brakes on (enough to lock them) when a car pulled out in front of me.

Immediately afterwards the brake pedal has gone spongy and the warning light is now on. Brakes work (ish) but pedal feels spongy and they only work with a couple of pumps.

I'm working away from home with no tools and no time so investigating properly is a challenge. I've looked under the bonnet and fluid level is good, well above minimum.

A quick diagnosis would be appreciated!

Thx

Any flexible hoses bulging?

I'll try and have a crawl around underneath tonight. The fact that I hit the pedal hard could have shocked a hose that was on its way out into a bulge maybe?

One of the two circuits has failed?
The valve thing on the front drivers footwell is supposed (I think) sense this and put the light on?

Went back to the car after work tonight to find a pool of brake fluid by the o/s rear wheel, and fluid reservoir now empty.
It was too dark to investigate further but the flexible line has almost certainly burst or de-coupled in some way. Needless to say I got the train home.

Car is now stuck at work and I need to either get it home to try and fix myself or get it to a mechanic to fix locally. Complicated by the fact that I live in Glossop but work in Birmingham..

Could this be a job for LandyZone International Rescue?

Sounds like the OS wheel cylinder/caliper or pipework has failed, and the dual circuit valve has operated. Do you have drums or discs on the rear?

Apologies - outcome was that pipe adjacent o hose had failed. New hard pipe fitted.

Time to look at all the rest and probably renew them all.
They will be the same age all round.

I know somebody that lives in Glossop. No help to you I know but thought I'd share it .

Close but no cigar.
