Firstly congratulations on your award
I used to live in Canberra 6 years ago and fondly remember knocking down some single malts with you. I am now in NW NSW .
I still own a blue shadow 1 two door car CHASSIS CRH2196 .I recently had an issue with a fire on the Front Left Brake. Have you any thoughts?
The fire seemed to be confined
around the grease on the sub axle and steering joints on the inside of the disc brake. It all looked pretty spectacular but hose water put it out and I drove home.
At no time prior did the steering or braking seem to be affected and I was driving in heavy Sydney Traffic. I am using Castrol 6336 hydraulic oil . Is that stuff flammable?
Iím a bit nervous about going out again until it gets sorted
If you get a chance please phone me on my mobile phone. 0414 623 250 anytime.

Sounds like pistons sticking in caliper, could be either one as there are two on each front wheel. If the grease for the wheel bearings gets very hot, it can leak out of seal at back of stub axle as on early cars= pre 17000 vin-ish, this seal is a scroll as opposed to a conventional seal that is more effective at holding liquidfied grease in.

Also check that the brake pads can move in and out freely. Sometimes corrosion on the guides for the pads can cause one of them to remain jammed against the disc (rotor). The resultant friction can cause things to get very hot.

Here are some comments about pads jamming in their channels from Paul Yorke - a RR specialist - which although about the rear calipers, might be relevant
"The part of the pad closest to the centre of the disc seizes in the calliper. This leaves the inner portion of the pads in contact with the disk once the brakes are released.
Initially this will lead to the inner area being worn thinner but then local overheating of the pads and discs cause rusting damage.
Every other year I remove the rear brake pads and clean the callipers and lubricate the metal to metal faces. The pads must slide in and out with just your fingers."

Steve how exciting. I assume your Shadow has quad disc brake caliper brakes like my Camargue.
I would take the car out with a fire extinquisher and quick lift aluminium jack in the boot with a friend and find a nice long country road without a cop, hit 100mph and do a harsh as hell emergency stop.
Have your assistant get out immediately and aim fire extinquisher at the mongrel and extinquish fire if there is one.
You should make your way to the boot grab the jack and raise that wheel as soon as possible then see if the wheel turns freely by hand. If it does not then its got to be one or both calipers sticking.
The only other thing it could be is either the wheel bearing grease seal is leaking and or the case hardening has come off the wheel bearings because of wear/lack of grease and grease has hit the caliper and then hit a red hot disc and ignited and or the brake fluid has come out of the caliper seal and hit the red hot disc and ignited.
The entire fire being in heavy Sydney traffic remains a mystery to me. Perhaps it was on that super hot day that Sydney had this year.
Most interesting post and a grim reminder to carry a fire extinquisher or two at all times.

Yes, fire extinguishers and a 12 volt refrigerator in the boot with strawberry ice cream and frozen carrots.
