3000M Front brake calipers

[Ron McC]

Afternoon All,

Can someone point me in the right direction for getting new front Left & Right brake calipers. Was there a donor vehicle?? and is the brake pipe a metric or imperial thread??

Thank You,

IIRC the Vixen & 'M' both use the Girling PB16 calipers. However I believe there is an imperial and metric version. The Vixen (up to '72) using the imperial version and later cars using the metric version. Don't get the wrong one as you'll damage the threads. The imperial version also had larger diameter pad pins which won't fit into the metric ones (vice versa they'll rattle around in the holes).

I just purchased a pair for my Vixen from ANG Classic car parts. They cost just less than £100 for the pair. I spoke with them to ensure I got the imperial ones and they seemed to know what they were talking about and happy to advise.

Rimmer bros will have them in stock and yes you have to check if the tread is metric or imperial.

Thanks for the info, However, Have cleaned up the calipers using a wire brush and 16PB is clearly marked on them. Now would these be Metric or Imperial, the car is a 1979 model??

If your replacing the calipers I would also replace the flexibles and link pipes, so you can make the links pipes up to suit the caliper.

A '79 car should be metric

An easy way to tell whether you have metric or imperial calipers is to measure the diameter of the pins that hold in the brake pads. If they're 4.5mm they're metric. If they're 6mm they're imperial.

Or measure the thread on the fitting you took out

Maybe you could get the Calipers cleaned then fit stainless Pistons as an upgrade.
