Customer Question
My 79 blazer was...

My 79 blazer was sitting for ten years without moving or anything before I bought it the breaks went out on it and I can't seem to find the reason why the break pedal goes all the way to the floor and it won't stop at all I checked the master cylinder it's fine the break lines fine as well calipers fine so I don't know what to do

Mechanic's Assistant: Have you checked the fluid? How old are the brakes?

Yes

Mechanic's Assistant: Are you fixing your Blazer yourself? What have you tried so far?

Yes I am I've tried bleeding the brakes I changed the fluid I used dot 3 fluid when I replaced it

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Do the vacuum lines have to do with the breaks as well
