Pedal ratio x pedal effort divided by area of master cylinder ( r2 x pi) .
3:1 x 100 divided by 0.312 X 0.312 x 3.142 = 300 divided by 0.30 = 1000 ?
Friend has a T with full disc set up that requires min 1000 psi to stop. His works with 5/8th m/c (ie 1000psi) .No idea how as it doesn't move enough fluid nor does it have residuals to stop bleed back. I think his pushrod is a tad too long keeping the recuperation seal closed so the pads are barely off the disc.
I must get lost in the translation from metric to imperial? 3:1 x 100 = 300 3.14 x 9.5 x 9.5 = 283.385 sq mm x 0.00155 sq in = 0.439 sq in 300 / 0.439 = 683.37  I don`t mean to be totally anal lads but you are missing some brackets in your equations. If you calculate as you`ve written you don`t get the answer that you think you do. Remember all figures in the brackets are calculated first then the sum of that takes it`s place in the whole equation...................................................................I`m off now, I`ll leave by the back door so no one sees me  |

It took me long enough to find the = sign, don`t start throwing brackets into the equation And i`ve spotted the discrepancy  |

what type do you want i,ve chucked some in the last skip,,,
but could be some left
the first type shown in terry,s link is also a very common landrover item so is available from paddock motors at a fraction of the ebay price
the second one in the link is everywhere from ford escort ,p100,,,transit.... to vw caddy,,,lt and the like..

Hi Tel.
Looks very similar to the VW camper one, though I'm not sure if all the ports are in the same places -not that it matters if we're replumbing it. Not a lot of room under the floor & I'm already going to have to notch a chassis cross member to fit the bus one as it's slightly longer than the Beetle one we've got fitted. The camper van one has the same mounting as the current Beetle one, so at least it should fit straight in.
I've texted forum member PD, who's a mechanic at a local garage, to order one for me at trade price, which is about the same as that Ebay one, but not had a reply from him yet.
My day off today, but been awake all night with horrendous toothache & a migraine. Finally got to sleep when Taz left for work, so only just woken up & feeling distinctly fuzzy! So no workshopping today. My next day off's Monday, so will be back there then.
I'm still cleaning old paint off the alternator & have got the stainless pipe to fit the Cherry Bomb silencers, so can make a start on those. Also still playing with panels under the dash, plus reworking the gearbox tunnel. Loony's busy with customers' paintwork at the moment, so I'm building up a collection of parts for him to weld when he's ready.

Alternator all cleaned up & refitted. Shortened brake pedal welded back together. Extra exhaust tubing started on. Dashboard panels trimmed & gearbox tunnel being reconstructed. We ran the engine again this afternoon -until it suddenly stopped. Turned out the earth terminal had come adrift from the fuel pump. Love the way the whole truck lurches to one side when we blip the throttle |
