After changing a rear caliper and disks and pads, I have a virtually non existent brake pedal. It still brakes and engages the ABS, but there's a frightening amount of pedal travel before anything happens. Anyway MOT due tomorrow so wanting to do a pressure bleed tonight. I can use the machine at work to do the job but they only have the resevoir cap size for BMW. My cars across town till I pick it up tonight, can someone measure the inside diameter of the resevoir cap on their car and save me a headache and pointless journey after, I'd appreciate it very much. Cheers
