On Sunday we headed down to the city to visit the son for lunch, a few sets of lights from his house the brake pedal was getting a bit spongy. A few corners from his house I was using the hand brake to stop. I was thinking it might be some sort of heat issue so we took his car out to lunch.
When we went to leave still no brakes so he had to drive us 100km to home. I returned Monday with a trailer and towed her home.

Ordered a refurbished master cylinder at 3 pm Tuesday and had it here at 11am today. (Wednesday,not bad since it was 2000 km away and we live in a rural area.)
All sorted and crisis averted. The whole situation could have turned out worse depending on where the failure took place.

The pedal went to the floor once a couple of weeks ago, I should have taken that as warning something was wrong. I bled the brakes then and all seemed well so I assumed I must have some air in the line somewhere.

 

More likely the seals in the M/C just failing.

 

Yep that was it. New master cylinder and we seem to be good. Done about 100 km and all is doing what it should.

 

Close call there Clarke.

Cars seem to GAIN speed when the brake pedal hits the floor, scary as.

Doug be good with shipping, well done.

 

Can’t thank Doug, Bill and the guys at Jagdaim enough. Always on the ball when you need them, out of trouble within 24 hours. Last time it was chasing cam bearings for the XJ6 36 hours before a track day in the middle of an engine swap. We got to the track 25 minutes before scuteneering closed, top blokes.

 

Bugger, it happened again. Headed the 100 km down to the city and all was good. After 20 minutes in stop start traffic pedal to the floor again. After a 10 minute break the pedal had some feel again so I headed out the freeway on the other side of the city 40 km to Dr Phil’s place. All good for now.

Dr Phill stuck his head under the bonnet and gave me a diagnosis in about one minute. The rear brake line passes very close to the right exhaust manifold. The line was out of it’s clip sitting about 2 cm from the manifold and the heat shield rivets had come apart and the shield had dropped down onto the cross member.

After my 3 beers I had driven 2 hours to have with the good Dr I tested the pedal and headed for home. Taking the toll tunnels to avoid city traffic and all was good for the 1.75 hour drive home.

Today I wrapped the brake line in fibreglass heat shield wrap and fixed it back against the inner guard and fixed the heat shield back in place. Now about 5 or 6 cm from the manifold with two heat shields. Time will tell if boiling the brake fluid was the problem.

 

BUGGA.
