i was out driving this week and i have develop a squeak when pushing the pedal , i have tried to lube things on what i see , i think it might be on the inside ? i never took a booster off the master cylinder before ,, i just dont know, its not the pedal pivot,,its kinda like a air sound too ,, i have great breaks ( power ) ,, do i need to take the booster off the cylinder ??

thanks

 

You need to put in a good sound system with a lot of volume!

 

i am going to contact the people i bought it from , got to be something going on , kinda like air breaks lol

thanks

 

i called them to day and they want me to check the check value ,, it was fine , no leaks , i did the test on it and while it was not running it made the sound until it pumped up and it stopped , after i started it up and it sucked more air it started to make the sound again ,, so i guess i call them again

 

It sounds like the booster has a vacuum leak.

 

i have check the check value , and it holds ,, if i take the master loose and side it out will i see anything ? or is there anything else to check,or do i need to just replace it

thanks

 

Check valve is cheap and easy to change. Check rubber seal it plugs into and vacuum hose for cracks. I've never seen a booster itself develop a crack or leak unless over tightened when installed. Do you have a dual diaphragm booster? If so maybe one diaphragm is ruptured?

 

thanks ax
i have looked at that also it seems to fit fine ,, real snug ,,i think you mya be right about the dual diaphragm booster,, if one is bad would i still have good breaks ?? make sense for sure

thanks guys
