If you could not get the pedal up from the floor I fear your other seals may already be toast, but it might be that the master cylinder just leaked dry. We will both pray the prior owner did not try to use Prestone or Bendix or some American brake fluid that ate out the rubber seals. How bad were those parts in the master cyclinder? The correct Lucas Castrol Girling repair kit is No 1974/xx, and you apparent got it. The two rubber parts crucial to fix master from your kit are clearly visable in your photos. The big rubber seal you said was too big is the right one. You will put the "flair" to the back and carefully fit it into the bore using the proper brake fluid to lubricate it as you work it in -- pressing the lip into the bore without tearing it. But first (1) you will fit the other smaller rubber cup on end of the piston shaft by unclipping and taking that apart. There is also a small spring under that in the kit (should look like a metric spring washer black spring material). That rear cup keep you from pushing the fluid back up into the reservoir when you appy the brake. It shuts off the intake. Replace the small spring if you find it in the kit. If not, be sure the spring is still strong and workable. (2) It is important to be sure the insides of the bore are smooth. I suspect you could handle that with emery cloth and your finger and do that before tearing the big seal trying to put it in. Be sure the flud lubricant on assembly is LMA Castrol to avoid either dryness or any cleaning solvent damage. If you are lucky the wheel cylinders might still be okay. If not get back to me and I will give you contact info for guy in midwest who sells Girling repair kits. I am not sure your brakes on the wheels themselves are disk all way around? At least on the back? If not, do you have double or triple shoes on front? Some of these European versions have different configurations. Lets just hope the kit fixes the problem so you can zoom around in your hot car. Should make you forget your BMW quickly. Jay
