hello  
I need help

a car w/ no power brakes functional  
brake booster = power brakes?  
what cna the problems be? can it be easily fixed?

could it be the brake lines?  
master cylinders?  
could it be the wireing harness?  
brake booster?

does 240s have probelms w/ the master cylinder?  
usually if all the power brake fails, I shoudln’t be checking the lines that go to each brake… where should I check the lines before it separate into each brake?

are brake lines easy to repair/replace? cheap to buy?

oh and… where are DOT 3 brake/clutch fuild sold?

thanks

thanks

how can I check the “check valve” ?

is there easy ways to check if the master cylinder still works?

oh… having power brakes not working. does the idea like having no power steering applies to brakes? like it’ll still brake w/out the power help?

I drove the Hammy for a few weeks with no assist and it still stops…sorta. You just have to really push really hard.
