In 50 odd years of bleeding brakes without using any thing other than a ru=
bber or plastic tube going down to a jam jar (preserves jar) to collect the=
fluid pumped out, the m/cyl cap has been OFF the master cylinder and no fl=
uid has ever splashed out, no matter how hard I've pumped. When you press t=
he brake pedal the level in the m/cyl will will drop very quickly and you n=
eed to keep an eye on the fluid level - with the cap on you can't see the f=
luid level.
You can bleed drum brakes without the drum on but you need something to hol=
d the pistons in the slave cyls such as a clamp or you can wire the pistons=
in. Occasionally useful to do when a slight leak in the slaves is suspecte=
d or you are building with the car on stands.
I had a pit mechanic, when time was of the essence, bleed a rear brake by s=
lipping the slave piston out past the seal lip, and whilst the pedal was be=
ing pressed and the cyl filled with fluid slip the seal and piston back in =
place - it worked and it cost a lot in fluid !
Linda - please remember that brakes are a bit of a life saver both on your =
side and on other peoples - they need doing properly. You errors and questi=
ons show you do not have much knowledge in that area but they do need doing=
correctly. Having a full understanding of your braking system is really es=
sential before you start with brakes. You should not learning on the job. F=
or your sake, let someone else do them.

I always leave the cap on the master (it's vented). =C2=A0If you leave the=
