I have had my master cylinders redone twice at goodyear and they seem to go out within a week.?

Question

i don't know what the problem could be if they keep being redone. i need answers

Answer 1

Could be faulty parts which DOES happen. Grab a different BRAND. Where all the lines replaced too? Often people think that ONE part fixes everything when in fact there are other issues. If you are not satisfied with what Goodyear is doing, find another mechanic.

Answer 2

Go to a different shop and have them check the entire brake system.
