Clutch Master Cylinder Replacement

The Midas location on 4th Street North and East Bay Drive in Clearwater are franchise locations operated by Adam Ford. These 2 locations were great while they were managed by Midas Corporate offices headquarted in Illinois. We were customers there at the time. Then, all went downhill when they were turned over as franchise operations, managed by Adam Ford who brought his swindling business ethics from .... the other side of the pond. The 4th street shop replaced a clutch master cylinder in May 2013 on our Chevrolet. It failed 10,000 miles later in July 2014. Under the terms of the warranty, they replaced it free of charge, again with an "after-market" part and not original equipment. The part failed also 10,000 later in May 2015. Guess what? It failed again in May 2015. We contacted them for a THIRD resolution. Keep in mind, their incompetence is now dragging on for 2 years ....They kept the vehicle overnight and said they had flushed the hydraulic clutch system and so, it should be good ...But it's not good, the clutch pedal is unresponsive... . I think 2 years and 3 separate opportunities to diagnose and install reliable equipment is ample time to decide on a Auto Repair Shop's competence, honesty and business ethics, don't you? By the way, we have taken our chevrolet to 2 other shop for evaluation and they recommended to only install Chevrolet original clutch master cylinder because after market parts don't last. Hum.... seems no one at Midas could figure that out and suggest this .....
