Bleeder hoses used to come with replacement master cylinders.

When I had my Shop I always had to keep some made up from old pipes cut off a junker .

The small hoses came with the motive power bleeder.

I also tried to get some tubing from AutoZoo, but upon opening the package, the hoses where tiny and didn't fit anything.

You can find the tubing at home depot or lowes I don't know the size unfortunately. For the fittings, they where from the dorman bleeder kit, which btw is horrible. It comes with a TINY black hose and you only get one of each fitting...

$20 for two plastic fitting... Lesson learned, you can build it better and cheaper.

Again, you can get these fittings in metal for a lot less at home depot or Lowes, and they won't leak on you.

Thanx guys .

I'm a Journeyman mechanic and I've installed probably 1,000 + ATE brand MC's and never saw one with these pipes .

I have several Motive brand pressure bleeders, none of those came with the pipes either .

Back to the junk yard ! ;) .

Good it is fixed. I was basing my diagnosis partly on the low pedal occurring immediately after a brake pad / hose change.
