I finally bled the brakes today, the last system now complete, just painting and tidying to go now, got the SVA forms ready.

Sunday afternoon, on a deserted industrial estate with a fully functioning car, fuelled up.....................................



WOW!!!!!!!!!!

A few days over 2 years, 3 different locations (parts of the time problem - while outside, I lost about 5 months due to weather).


Bleeding the brakes was a minor problem, I used an easy bleed, but it just would not rid the system of air, I borrowed a young painters girlfiend to sit in the car and do exactly as she was told(!). I got her to pump up as much pressure into the system as much as she could then hold it as I released the nipple. Fluid gushed out.(this does not sound like car building, does it!!). I went around the car a couple of times until she said it was rock hard, I tried it, and she was right!!.....



The brakes now work really well, the pressure and feel is just about right, I can brake really hard and make the wheels just lock up by curling my middle toe. This was a bit of a relief, as someone here told me that the system would never work as I was using a master cylinder from a servoed car. I have used the whole sierra pedal box and master cylinder with the servo removed, and the MC just bolted to the pedal box. The original sierra push rod fits exactly into the master cylinder instead of the servo.

I trundled the car around for about 1/2 an hour at low speeds to check that nothing fell off - then I floored it. A 200yd straight with a brick wall at the end

Running at 5mph with the clutch engaged and pow. The revs hit 6000 instantly, an insane howl from the exhaust and she was flying, she never really gained full traction in first so I changed up. 6000 again and still flying, got traction just as I had to brake for the wall, the harnesses were the only bit of the car still touching me. I did a quick 3 point and did the return run - this time a bit more carefully. Feathering the throttle to just keep traction, I just managed to get into third before cutting myself into 4 with the belts.

6000 in second is 56mph - in 200yds less the braking distance. PURE ADRENALIN


Then the fuel pump jammed again. I now have to fit some sort of prefilter for the pump, its the second time it has jammed. I could not free it this time by reversing the current, so I'm off to the scrappy to get a new pump and here to get some ideas for a pre filter.

A VERY SATISFACTORY DAY

The tank was made about 8 months ago, I also used severe amount of amps to make sure it did not leak, I suspect weld scale on the inside of the tank becoming detached. it could also be a dodgy pump, it had done 113K miles before being relocated!

stephen_gusterson - 24/10/04 at 10:28 PM

mine was made by someone at the company my dad worked at before he retired. its been TIG'd.

also, it was 'seam welded' on outturned flanges. kinda like the way that mini wings and rears were welded on - there are basically external flanges poking out 10mm all over the place. perhaps that will trap weld crud.

ive had a thought. we use filters at work. we use these to filter very low viscosity oil which is fed by a pump producing very low pressure. you can easily blow thro....

it uses a nylon insert as the filter, and it has a screw off bowl. not sure if its petrol resistant, but its certainly ok with oil. we screw hydraulic fittings on to it that could be altered if they dont fit 15m pipe.

let me sort one out tomorrow. think we might both need one. i can likely help you out as a freebie. might cost a ride in your car if you turn up at any shows tho

bloody ideal, would save a load of time and headscratching - thanks

Mark

stephen_gusterson - 24/10/04 at 10:42 PM

dont know why i didnt think of it before.

id suggest sticking it in petrol for a week or two before comitting...... just in case it does self distruct!

will see if i can sort summat out. ive emailed myself at work so i can remember!
