Group, my C-300 has twice this summer had failure on its freshly overhauled brake system. On both occasions the Kelsey Hayes master power brake appear to lock up and not letting out the vacuum after I have released the brake pedal. Brakes stayed locked until I split the master cylinder from the booster. Anyone seen this before, any remedy? Additional information: The lightest of touches on the brake pedal sucks it in and make immediate contact on the shoes, making progressive braking a difficulty. This was evident both with the old (original) and overhauled (x-55 De Soto) K-H MC. Having just gone through the brakes on 29 Chrysler one really wonders if there was any progress at all in the intervening 26 years..
