Comments about CARQUEST Clutch TECHnovation Clutch Master Cylinder:

Started leaking 2 days after warranty expired, [...] Leak ruined my floor mat and I was forced to buy another part from Advanced auto because I was broke down and no one else had it in stock. Now after 10 months, this replacement is leaking again. These parts are garbage.

      Comments about CARQUEST Clutch TECHnovation Clutch Master Cylinder:

      I bought this because my set up requires a .875" bore and this item actually has a .750" bore which doesn't push enough fluid for my clutch slave cylinder. Probably be great for a stock replacement.

        I just replaced the clutch, pressure plate,line and slave cylinder can a bad master cylinder cause you to keep getting air out of the bleeder valve?

          You must bench bleed the reservoir,master, and line as a unit before you even install them in the vehicle.

          I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem.
