Brake bleeding, waste of time?
 

Is it a waste of time to bleed the front brakes if one had only cracked the rear? I've always conformed to the old rule of start with the farthest wheel and work forward. However, on a split system (such as my 85) I don't see why I need to mess with the fronts if all I did was replace the rear hose.
What say you?

Yes, I agree it’s a waste of time. The design of a dual master cylinder is just that, one chamber will remain intact in the event you lose front or rear brakes. There are a lot of theories out there about two cylinders but one piston, one will bleed to the other, and whatever else people say.

The best way to know is to do as you said with bleeding only the rears and test the brakes.

when was the last time you flushed the system out.

I've often heard you should change your fluid every 3 years or so. Unless you've been in there recently, it might be a good idea, just to get some new fluid through there.
