Question about 2012 Toyota Corolla
Posted by Anonymous on
I assume you have brake fluid in and you drained the lines?
you should not change vacuum nor master on three years old car! baring accident - these two parts are rather long lasting
did you try to pump fast in succession about four or five times brake pedal? is it going stiff after pumping?
did you try to bleed all lines? on every single wheel?
start with rear wheels (furthest from master cylinder) and bleed about half cup - or if bubble are present till bubbles stop. do not forget to check level in canister while you are bleeding the brakes! two persons are required for best results..
repeat on all wheels.
check for any brake fluid loss on any point of the lines or on any wheel. if leak find - repair and bleed again. do not forget to use correct fluid.
if you find this short advice helpful - do not forget to vote...

You didn't say so I'll ask. Did you bleed the brake lines? Any time you deal with brake fluid replacement you need to do this. Air gets trapped in the system and causes exactly what you are describing.
There are several methods to drain fluid and air from system. I have used both the vacuum method and assistant / friend method. Here is a video on YouTube which shows the methods. You can search for more detailed videos if you want.
Make sure you have the correct fluid for you system, Dot 3 or 4 most likely, and make sure you have plenty of it since you don't want to get half way through and run out. You can always return unopened bottles for refund.
Hope this helps.
