Brake bleed ?

[ttwlr]

I'm looking to bleed my brakes by myself and want to know what size clear tubing to use to get a tight fit ?

I too am trying to bleed brakes on the new ‘59 pickup, LHD. I have no pedal. Successive pumps bring the pedal up to about 1” from the floor. Im working alone with a miteyvac hand pump from the opposite rear wheel (right side). I’ve pulled several ounces of fluid out and still see bubbles. Im wondering if I am sucking air around the wheel cylinder cup, the master cylinder, or bleed valve?
Haven’t found any leaks yet. The previous owner claimed the brakes were working when it went on the trailer. I fear the master cylinder might be shot and I remember what a PITA they are to replace.
Any diagnostic suggestions?

Try pumping until you have the firm pedal then wedge a piece of wood between seat frame and pedal. It will keep pressure while you check for leaks, always easier to see fluid leaking out than air leaking in.
You could also try putting the bleed tube into a container with fluid covering the pipe end and pump the pedal to push fluid rather than sucking it through.

Thanks Bill,
I don’t know if it was the tube in the jar that worked or the 12 ounces of brake fluid I flushed thru but I have some pedal now. It’s still lower than I would like. There’s about an inch of dead pedal travel before any resistance. Not sure if the push rod needs adjustment? Don’t understand why they failed in the first place? Oh well, tomorrow.

I found part of the dead pedal movement. The pedal has bent the floor plate upwards. I hammered it down and most of the free play went away. Do I correctly recall that there was a rubber buffer/grommet in the opening?
