After sitting for a while the brake pedal now goes to the floor.
Does the dipstick for the master cylinder unscrew or pull out from the tube? Neither way works for now
It's a totally different system to my Mopars
Apart from the booster m/ cyl is the rest of the brake system the same as your every day car?
Who are a good source for brake parts as i might need to rebuild the m/cyl and any other parts that might need attention? I'm in New Zealand
Any additional info would be appreciated
Thanks in advance

I have a 69 cutlass I have put rear disc brakes on and cannot get any pedal on car, let me re say that, You can get a good pedal from pumping the brakes, leave it alone a minute and goes away, But can be pumped up, It was a kit, have also replaced the master cyl and prop valve twice, have stainless hoses, from what I can tell is the brackets on the rear must be a little off to where pushing the caliper pistons back too far, I have tried dragging the parking brakes on the lift to try to seat the rear pads in to no avail, have completely blocked rear brakes and have a great pedal, Any one ever run across this situation? ]]> Brakes/Hydraulic Systems Misfire https://classicoldsmobile.com/forums/brakes-hydraulic-systems-9/69-olds-cutlass-rear-drum-disc-complications-191381/
