Metro turbo calipers

[v8ian]

I'm working on lots of things about brakes at the moment. Metro Turbo calipers??? can anybody tell me the dimensions of the discs they fit, thickness, dia, I have a plan??? possibly

[chairchild]

I would've thought they'd be like gold dust nowadays?? They're also chuffing heavy for what they are...

Diameter: 213mm
Height: 71mm
Thickness (new/min): 20/18mm




IIRC, Mk1 Fiesta Calipers are a single pot sliding-caliper design (much lighter, and just as good really) and they're used on minis to good effect

[trouble]

Loads about. Set here if you need some.

They where a 4 pot set up.

When we had a Metro City (D reg and 6 months old) the calipers were the same thoughout the range. That meant the 1.0 base model and the turbo brakes were identical. Not sure if earlier or later were the same but annoyed me having to buy the more expesnive (at the time) turbo spec pads for our 1.0 shopping cart.

Yeah, metro brakes are all the same, they came in vented or non-vented, and the calipers are the different (although I believe non-vented ones can have a spacer put between the 2 halves to work with vented discs), but it's not just the turbos that got the vented brakes, I think it's the higher spec early ones, and all the later ones.

As said they're a bit heavy, I wouldn't say they're a LOT heavier than the fiesta brakes chairchild mentioned, they're quite small calipers for a 4 pot, but there is a weight difference. The fiesta pads are actually more now if you want any sort of performance pads, and on a mini you need machined down discs, so the discs work out as a lot more. (I've got a mate who's changing to metro brakes from fiesta on his mini to get the running costs down.)

For an iron 4 pot they are light, you won't find much lighter IMHO.
Around 3kgs each, a Volvo 240 caliper is 4.1kgs for instance.

I knwo they'll take a 225mm disc on the cars I run them, but obviously it's mounting dependant.

I have looked a bit further into this and think the calipers might be too small for a 265 disc. I'm looking at Mk2 granada Vented Calipers now,

RX-7 FC?

Hang on a second. People are dismissing Metro Turbo Calipers yet hail Princess 4 pots which have a smaller effective piston are than a Ford M16 caliper (with the added weight to boot) :/?

[v8ian]

I'm dismissing them because they are for a small dia disc, which means the internal leading and trailing corner of the caliper where the disc fits will hit on a larger disc before the caliper fits fully onto the disc,
Princess and M/P 16 calipers have almost the same piston CSA but have the benefit of about 50% more swept pad area. I'm now looking for a pair of M18 vented calipers??

[ChasR]

I was getting at how people seem to believe Princess 4 pots are better M16s, despite as far as I can see, there being no real gain, if any.

Fingers crossed that the M18 caliper does the job . How about Mondeo sliding calipers?

[v8ian]

M18s have the same piston size as the 16, but as much pad area as the princess, could be a winner, I'm not a lover of sliding calipers, I know CapriSport seem to use them with success,
