Ok, so just some quick history....I have a 2003 Jetta with about 120K miles. Last summer I was noticing about every month or so my brakes would be very hard to depress and I would almost need to STEP on the pedal to get the vehicle to stop. I figured this was because I hadn't changed the brake fluid in the vehicle....ever!
So I then did a complete brake bleed and replaced all the OEM fluid with ATE Super Blue (http://www.ogracing.com/ate-super-blue-brake-fluid) and flushed the whole system using the Motul Power Bleeder (http://www.ecstuning.com/Search/SiteSearch/Power_Bleeder/ES3474/). This didn't seem to make a big difference and the issue seemed to get more frequent when I would have to put a huge portion of my weight on the pedal to get the bakes to respond. It started happening about 1 our of every 10 times I would use the brakes and I started worrying that the brakes would eventually fail.
Just yesterday, I installed a brand new Brake Master Cylinder (http://idparts.com/catalog/product_info.php?products_id=767) from IDParts and again flushed the whole system including the clutch. After doing this, the pedal is less responsive, sometimes sticks (causing the brakes to almost lock up) and again I'm forced to put my whole weight on the pedal to get it to respond. I noticed that when I drive down the road and I initially press on the pedal, there is a "whoosh" sound of what sounds like air, then the brakes start to grab. I would normally think this is air in the lines, but I did bleed them acording to the instructions with the Motul bleeder. I'm REALLY hoping I do not need to replace the Brake Booster along with the master cylinder.
Any thoughts/suggestions?
