Hi list, I'm hoping someone out there can help me out with my brake bleeding
issue however, I'm sure you are all out enjoying your TR's while i sit it
the garage watching air bubbles all day.

What I'm trying to accomplish is to transition from DOT 3 to DOT 5, i have
speed bleeders and I've tried to bleed the conventional way with no luck so
i am now using an EZ bleeder system that uses the vacuum created by the air
compressor in order to draw new fluids down through the system, still no
luck just bubbles.

Here is some history of what I've done to the car that brought me to this
point.
1. rebuilt calipers
2. new caliper pistons
3. new stainless steel brake hoses
4. rebuilt master cylinder
5. blew out brake lines with air after removing the DOT 3
6. ran denatured alcohol through the lines prior to filling the MC with DOT5


I've checked all the lines for leaks (visually) and there doesn't appear to
be any, plus i would see liquid spots on the floor.
One thing i did that might be important to this story (hoping it's not) i
had to spit one of my calipers in order to remove a fused piston however, i
replaced the small O ring between the caliper and used the correct torque(s)
when putting them back together. At this point i do not see any leaking of
fluid between the two half.

I've been working on bleeding my brakes for 3 days now and the air bubbles
just keep coming and the pedal is mushy. I'm hoping that someone out there
may have experienced the same thing and has some tips on how you overcame
the issue.

Thanks all,
Bill
