Changed the master clyinder and master pump couple times but never twice at the same time. This time im changing everything. My father wants to install everything outside the car bleed it then install it ? Do ya think thats a good idea?

 

i don't think u would be able to bench bleed the clutch system like u would a brake master. there's really no way to have resistance against the slave cylinder piston and it not mounted to the trans. if u can, find part numbers for everything so it's all new and not a reman.

 

And get a stainless steal braided clutch line instead of the rubber line.

 

These are paired systems; Master cylinder and Slave cylinder. Replace them both at the same time. What happens is that the new seals on the new component overpower the pressure of the older one, and it blows out. You think you installed a bad part, but the truth is that the older part has now failed.

No need to bench bleed, just install both cylinders and bleed correctly. They're not that expensive, and then you'll know you're good for anoher decade or so.
