Brake master cylinder

Post by Jiml » Sat Aug 29, 2026 8:14 pm

Hi All

Got a leaky brake master cylinder can't spot the leak probably a seal. Don't know if mine ia a single or a double. Probably best to replace it all, anyone know the part number for it.

Cheers Jim

Hiya Jim!,

The part number you're after is 569671. Shop around, as prices do vary from seller to seller for the same item. I have fitted two B######T ones to customer vehicles in the last year or so, and neither have been on the phone jumping up and down about leaks or brake failure. Rebuild kits are available if yours is a genuine Girling and you wish to keep it.
