Hey Guys,
I replaced the master cyl. on my 1974 280C and can not get rear calipers bled....front calipers are OK! Good pressure there.
The rear calipers just dribble fluid??? Any ideas from the old school.

 

first remove the bleeders from the calipers and check that they're not blocked, and then check your rear brake hoses.

Also note that you don't get the same amount of delivery to the rear calipers. From what I recall, the master cyl is stepped.

Did you bleed the master cylinder prior to installation ?

If not, they can be a ROYAL pain to get bled.
