On Feb. 19, I replaced the clutch master cyl. on my 240d. I used the brake caliper method to bleed the system.Within a week,the slave cyl. started to leak.My guess is that it was either borderline to begin with or the caliper bleeding method was too high-pressure and blew out the seal.In any event,I replaced the slave cyl. this weekend and bled the system using a 60cc horse syringe.I purchased one from my vet for $2.00 and it worked like a champ!I found this tip here on the post and it was an excellent idea!
