Alright so I've gotten a little flow to the back passenger caliper, wanting to flush the brakes as there was some rust in this caliper,on back of bleeder,...should I use denatured alcohol or just brake fluid I don't have any where near the correct amount of flow coming to this caliper

 

keep it brake fluid...just use a of it to flush out.

btw dont create a new thread for the same topic...you lose the history of your orig problem.

 

My bad ..long story short,it was the master cylinder

 

is this on a different car or same one as your other two threads?

 

Same car just resolving my issue for others
