I have a 2007 Mustang and I have lost my brakes three time in 2 years, was wondering if any one else has experienced this? If so please let me know.

Thanks John

Yikes! Not good, should still be under warranty. I'd have the dealership check it out.

What was the diagnosed cause of the failures? I'm really curious. Brakes usually are very fool proof.

Two master cylinder, now they think it maybe another master cylinder, ABS or hydralic control unit.

I Had That Happen To Me In My Old Fox Body, It Was An Internal Leak In The Master Cyl, Most Of The Time The Brake Would Work But Every Now And Then When I Went To Step On The peddle....Nothing Went Straight To The Floor Until I Pumped it Then The Brake came Back. Turns Out The Fluid Was Blowing By Some Of The Seals In The Mas Cyl. and The brakes Wouldnt Work Until Te Entire Mass Cyl Filled With Fluid....Scarry Stuff.
