Mechanics Trial

by Fred Gregory

Fred Gregory and Pete Stafford enjoyed The Mechanics Trial

Having competed in quite a few Cotswold Clouds, Pete Stafford and I knew that their Mechanic’s Trial was going to be a rough, tough event. We were not disappointed, and getting the chance to explore sections and tracks that we had never seen before, and had not been trialled for many years, heightened the experience.

The day dawned wet and misty. We were running quite early in the field; at number seven, so we hadn’t expected to see clubmates Michael Leete and Mike Hayward, who were among the tail end Charlie’s. It was a good job we didn’t hang around for them, because they didn’t make the start, when the Beetles front brakes locked on only a few miles from home.

Our adventure started even before the first hill. We were travelling in convoy on a long off road run-in to the first section when my Rickman Ranger got stuck. We were actually going down hill at the time and the car was well and truly stuck on its diff casing. We were stranded with our driven wheels practically off the ground. Clearly we weren’t going to drive off under our own power, so the ever resourceful Pete Stafford dived into the undergrowth to produce a strong tree branch that we used to lever the car off. Away we went towards the first section, not very far though, because just a few yards further on the track had been washed out. There was a triangular shaped gully up the middle with the sides at an angle of about 30 degrees. I tried my hardest to straddle it but the Rickman soon dropped in, to heel over at an enormous angle. Pete fell across on top of me but there was no choice but to keep my foot down. We scraped along with the side of the car wearing away as it rubbed along the side of the trench! We were not alone; one of the Moss Brothers in an Imp did the same, only he got stuck! I wonder how many other competitors followed suite?

The section was a no-no, too tight a turn at the bottom for us. On to section two, not so fast though as there was more off roading. Our convoy found a Cannon ahead trying to reach the tarmac road un-aided. Teamwork got him out, plus our entire group of six or so cars. Carl Talbot got all the way to the four in his class eight Trialsmaster and Ian Moss wasn’t far behind him in his Imp. Most of the entry was like me though, grinding to a halt at the eleven!

Some of the sections were sub divided, funnily enough we found these ones easier! The off-roading was great, the sections were often narrow, rough and challenging, absolutely marvellous stuff, never mind that two were abandoned.

By the time we reached the last section, called “Viaduct” we were running first on the road. The start was on a flat, deep leaf-moulded surface then a muddy bit, through a gate onto a soggy field, climbing, then harder ground followed by steep mud with ruts and it was sub-divided. We gave it full power. Pete on full bounce mode even using 2nd gear it was touch and go at times, a brilliant section. We stopped in sight of the section ends board for a one. No way out, it was back down to the start, nearly half a mile away.

While we waited for a way back to the road there was a medical emergency, a suspected heart attack. Nearly everybody had to leave to make room for an ambulance. We hoped the patient was OK but after the event we learned that he died.

The section was cancelled and the entry wound their sad way to the finish. A tragic end but thanks Stroud boys and girls we really enjoyed our Mechanics Trial.

Michael’s Mechanic’s

I was really looking forward to my Mechanic’s Trial, and so was Mike Hayward. It promised to be really interesting, the first “new” event for us since we did The Exe Valley a few years ago. It was particularly poignant for us as Falcon enthusiasts, as it promised to use some of the sections from The Guy Fawkes, back when it was a road trial in The Cotswolds.

by Michael Leete

The event was first planned as “The Anniversary Trial” to celebrate Stroud’s 50th. Andrew Brown and Rich Welch organised it as a day/night event, with relatively easy sections, with the emphasis on the team award. They had sought out a mixture of old and new sections in the Cotswolds, using the area to the North of “The Cloud’s” stamping ground. Andrew had done a tremendous amount of research, including seeking out some of the sections used on the old Falcon Guy Fawkes. The event was first called off because of floods and then Foot and Mouth got in the way. By this time both Andrew and Rich ran into time problems and the event was put on the back burner.

It was a waste to throw away all the hard work, so Stroud’s Hayward clan took up the mantle and the club decided to make their Mechanic’s Trial a road event. It was to use some of the defunct “Anniversary’s” route, but with some new ones to make it a rather tougher event, in the normal Stroud style. Mike and I had originally planned to do The Anniversary in Mike’s Escort but we entered The Mechanic’s in my Beetle.

The car had been resting in the garage over the summer and I hadn’t really done anything to it since The Lands End. It had gone well on The Edinburgh, despite the little problem when the brakes disappeared. The first time this happened was in the queue for Putwell. I went to move the car forward and the footbrake went to the floor! A pump of the pedal and there was a little bit of brake, another pump and it was back to normal. I leapt out of the car and dived underneath. No evidence of leaks. Up with the hood to check the reservoir, all looked well and the pedal was back.

We continued with caution and all seemed well. An hour or so later we were coming down a hill in convoy with Mike Pearson and Simon Robson and the pedal went to the floor again. Turning into a lay by we checked. Again there was no fluid loss and the pedal came back after a pump or two. I went back and talked to Mike and Arnold and they reckoned the master cylinder was on the way out. I decided to continue albeit at quite a slow pace! We finished the trial and drove home the next day with no problems. Back at base, I could find nothing wrong, although I noticed the front brakes were dragging a bit.

The next weekend I fitted a new master cylinder, which was bit of an effort, as the other one hadn’t been fitted properly. The pushrod passed through the double-skinned front bulkhead on the floor pan. It is only supposed to bolt to the outer skin, using a couple of spacers to extend the length of the bolts. The manual gives dire warnings about not dropping these down into the void. I didn’t, because they weren’t there! Someone had lost them when changing the master cylinder on a previous occasion! I used a magnet to fish about down the hole to no avail, presumably they had fallen out when I had a section of the frame head replaced in the early days of owning the car. 

The previous owner had secured the master cylinder by putting large washers under the bolts and securing the master cylinder through both skins, which without the spacers had collapsed the inner one in a bit. I didn’t want to repeat the error so I made a couple of new ones up out of a couple of bits of pipe, skimming them flat with the little model makers lathe I bought earlier in the year. I put everything back together and everything worked, except the front brakes seemed to be dragging a bit. I took the car for a spin and everything seemed to function so I put it away until the Mechanics Trial.

Mike and I set out early, chatting away, without a care in the world. We got to Ampthill, about ten miles away from home and I braked for a roundabout. Pulling away I smelt burning and soon realised it as coming from the brakes. We stopped and I saw how hot the front hubs were. Hoping whatever was wrong would right itself we carried, on but the car wouldn’t pull the skin off a rice pudding. Stopping we jacked the front up. The brakes were locked on pretty solid.

It was raining but we had good look but couldn’t come up with any better ideas other than the new master cylinder was faulty. I hammered away at the pads until they were free of the disks and we limped home on the handbrake. We talked of going down and spectating on The Mechanics but decided this was not a good idea as we didn’t know where any of the hills were so we went to the VW Swap Meet at Slough instead.

In order for the fluid to go back up to the reservoir when the pedal is released so the pads can go back channel A must be open which means there must be clearance b between the pushrod and cylinder.

Looking at the car the first idea was that I hadn’t adjusted the master cylinder pushrod correctly, preventing the fluid going back up to the reservoir when the brakes are released. I slackened this right off and it made no difference. Then I undid the bleed nipples, releasing any pressure, still no difference. Then I took the brake pipes off, still no difference! So that only left the callipers, which were only a couple of years old but there was nothing else. Putting the pipes back, I persuaded Lesley to get in the car and put the brakes on. I then got a drift and knocked one of the pads back. I got her to put her foot on the pedal again. The piston didn’t move. Harder and harder, she pushed and slowly it moved forward with many creaks and groans. I took the pad out and got my big crowbar and levered the piston back. We repeated the process for about ten minutes until the piston moved freely. I put the pad back and went on top the next one.

I was pretty annoyed with myself for not trying this in the lay-by but there we are. The brakes worked but I decided not to take any chances and got a new pair of callipers. Now all I have to do is stop the fluid leaks having undone all those brake pipes! So, why had the brakes failed on The Edinburgh? Murray’s theory is that they were rubbing then and that the heat had boiled the brake fluid. Any better idea’s?
