Type 16 brake caliper torque ?
UncleFista - 27/7/03 at 09:51 PM

Hi, a looong time ago I split my Ford type16 calipers (BEFORE I heard advice not to) I've refurb'ed 'em and they're ready to go back together.

My question is 'does anyone know what they're meant to be torqued to ?'

A couple of people have told me that they shouldn't be split, (presumably I've released the brake fairy ) but these types of caliper are split and spacers bolted in so they'll fit crapi vented discs so it MUST be possible to bolt 'em back together

Anyone have any advice or failing that, a theory on why they shouldn't be split ?

Cheers all

I think the bolts are "stretch" types and should only be used once and there's some debate about whether the internal drillings will line up properly.

others may (will) know more.

Cheers

The bolts/cap screws will be of a very high standard. Do as the man says, and replace them. If they're imperial, buy grade 8, and if they're metric, buy at least 10.9 standard.
The absolute best ones for the job are Waspaloy fasteners. They're rated at 150,000 PSI, and can withstand 1600 F.
Torque them to the recommended torque for the bolt material/diameter.
There's a bolt torque calculator on my site in the Tech Page.

Fista,
Went into work 2day to get the accurate data. There are 2 sets of bridge bolts on an M16 caliper; for the smaller, torque is 68 - 54 Nm, and for the larger 95 - 75 Nm. I made enquiries about obtaining replacement bridge bolts, but the factory doesn't carry them anymore. It's all down to the service arm of TRW, and I've no contacts there now.
Why "Do not separate"? Difficulty in obtaining correct grade bolts, and replacement transfer port seals.
