August Summer Driving

Changeable weather for the month reduced options for driving the Corsair as I hoped to take it into work for a decent long run. However, the brake seizing problem was seemingly cured (weekend 10/11th) by replacing all the brake fluid in the system with new DOT4 fluid, my grown up helper assisted with pedal pumping and fluid top ups. Thinking about it, the fluid was last done 3 years ago and quite probably had ‘gone off’ with water absorption which reduced the fluid’s pressure tolerance. A 20 mile test drive around the lanes of Hindon to Tisbury was a good try out which didn’t reveal any problems.

Another bonus this month was my success at winning a hotly contested Ebay auction for a rear view mirror. Original, good condition mirrors for the Corsair and Mk1 Cortina are quite rare to find because the plastic becomes brittle, crumbles and the silver mirror backing often deteriorates just as per mine. Saturday morning (17th) I had a decent run out to Westmoors, 40+ mile round trip, in the Corsair and it was a good run with me chasing the traffic rather rather being stuck behind part time drivers and no problem with the brakes. Later, I fitted the mirror and what an improvement that was. Later drives with the new mirror in place was that it didn’t wobble as much as the previous one and I did have better general view as well.

A drive out one Thursday evening brought back the dreaded brake seizing issue again. it was brisk, spirited drive up Zig Zag hill an then along the back lanes towards Cashmoor and the ‘Gussages’. However, I had another event of slamming on the brakes was required after a near head on with a tractor. This may have upset things a bit with the brake system, because on the way home and going back down Zig Zag Hill I could the feel the pedal become more firm and the further I went on the steering vibrated more as the brakes seized on again. I just managed to get the car home without a forced stop. The next day I re-bled the system just to ensure it was air free and took it for another drive to Sturminster and Durweston then home anlong the A350. Again, after about 22 miles the brakes became hot and the Corsair became difficult to keep going. I pulled over about a mile from home and checked all the wheels for heat. The rear wheels were fine, but the front wheels were very hot, not just the discs but the rims too! I have ordered new brake discs and pads, as the current discs were rusty and pitted and could be binding therefore causing heat to build up and thus raising the brake fluid pressure in the system?
