Standard caliper bolt length?

[Brummmie]

Hi Guys,

I need to order new bolts for the 330 kits, can anyone confirm the standard length of the bolts that pass through the calper, to the alloy block on the upright, mine are long gone!
Whatever they are i need to order plus 5mm to allow for the spacers that should be finished this week.

Thanks

75 mm including the head.

Bolt list says 60mm
Mine were 65mm when I removed them so I replaced with 70mm, but at 75mm allows a bit more and could be trimmed if needed.
5mm spacer puts the pad over the edge of the disc by 1mm. So 4mm is better.

I can only order bolts in plus or minus 5mm, but yes the spacers are 4mm.
If the bolts are too long we run the risk of bottoming out on the upright, too short rip the threads out.
Looks like i must try and find an original car to get a diffinitive answer!

I have to do a special order on these, as they are an unusual thread, i have to buy a whole box that then has to come from Germany so aint cheap.

They dont do 75mm...
Which is what we need, their 80mm ones are £8.00 for four, however....
I have ordered 75mm ones from a local distributor and they will be £6.00

Spacers with bolts will be £25.00, i have the spacers in my possesion as i have just picked them up.

Good Result!

Looks like you will get 330 up and running before me.

Life keeps getting in the way, been two months and all ready to bolt up and bleed after new caliper seals and 330 upgrade! Hey ho...
