cheers dave best u2u u a list as there are those other bits. im going to have a play tomorrow if its not raining.

spent all day outside today making all the wiring under the dash beautiful also had to sort out my horn. depending where the steering wheel was changed if it worked or not. took the wheel off and it was clearly obvious that the terminals were corroded. quick sand with a bit of wet and dry and problem cured.

getting all the lights on the dash working and doing what they should be doing felt absolutely fantastic. i can happily say all the electrics are done and im more than happy with them.

next job is to config the speedo. apparently according to the dash manual you just enter the wheel diameter if the sensor is on the wheel and it calculates the speed from the wheel rotations. the only problem is i have mounted mine on the prop flange.

being on the prop with a diff ratio of 3.92 means for every 3.92 turns of the prop the wheel rotates once.

so theoretically if it take the wheel diameter and divide it by 3.92 the speedo should be dead on.

ash hows your brakes? sorted yet heres a few of my ideas

whats the deal with your pads etc if you have new pads on old disc you will get more travel at your pedel even with new pads on new discs
get them bedded in if you can

ajust up the rear drums as much as possible (are the shoes new)

check your discs and drums are running tru (use a dti)
i have had this loads of times on new brakes

all your calipers sliders free if your on single pots or all your pistons free on multi pots
or just not aligned corectly?

if its all bled ok (must be by now) you should start looking at lost movement

not sure with the iva but the mot rule of thumb was if the brake efficency was in well berfore the end of travel stop it was fine the old fiesta's where bad for this as thay put the master cyl on the other side with a link rod and it would twist under the strain

[AshG]

i think its sorted. i have got a funny feeling that the mc is just a little on the small side combined with un-bedded parts. took the car out for a test stop and i can lock the wheels very easily

i think the excess travel could be contributed to by the fact that the pads and shoes are not bedded in yet. i have a new MC, new discs pads and callipers on the front then new shoes and cylinders on the back. the only bit that is not new are the drums. they had a bit of a lip but i wouldnt have said it was bad.

will see what dave thinks when i comes over. i could go and get 2 new drums but it may be a waste of money.

Grind the lip off and click the adjuster's up manually,much better pedal than letting them self adjust.
