What are people talking about when they say the master/slave cylinders have broken numerous times, in reference to the plastic ones.

Do they mean they broke them during installation?

 

they refer to the plastic slaves doing a little pop.. happens alot when you dont have the slave connected and you push the pedal.. the slave will be fully extended and the fluid will have no place to go so it pushes and basically pops the bottom off, cracking some retaining pieces in the process..

 

why would you push the pedal without the slave connected.

they make it sound like you NEED to buy the alum. versions of the master/slave cylinder.

well if it was just installed correctly it should not have problems correct?

 

i did it once because i was playin in the drivers seat with no motor..

it could also be that the plastic stretches under pressure and can crack.. but an aluminum is a pretty good idea since its only like $34 from summit.. i just upgraded to the aluminum one.. overexagerating, powershifting became alot easier..

 

ya but the stock unit i had lasted since 1988...

...and i drove the **** out of that thing, heh

oh well. i was just wondering if there was some MAJOR reason to get the alum. ones, since I already have the GM replacement kit sitting in my closet, cost me 220$ from hawks, but its all one unit preassembled.

 

no real reason to upgrade.. its just that if it does break, might aswell get a better one that more durable.. i got mine because we were having problems with the hydraulics.. couldnt powershift for crap.. so we figured we try out an aluminum unit because it has the brake bleeder screw on it for easier bleeding.. and it worked
