    Comments about CARQUEST Clutch TECHnovation Clutch Master Cylinder:

    Product installed and works perfectly. It has only been installed for about a month. No leaks, full pressure to slave cylinder. All the reviews that state, "the pedal goes to the ground" aren't reliable information because that happens to every master cylinder that has air in it. If you bleed it right you wont have air and the pedal is firm after 2-3 pumps, not having to pull the pedal up at all by hand. Bench bleed if you can.

    Extremely Disappointed

    Comments about CARQUEST Clutch TECHnovation Clutch Master Cylinder:

    This is absolutely the worst car part I've ever bought. I went through three of these and each one had a leak in it. I even took it to my mechanic who worked on two of the three and still no pressure in my clutch. Please avoid the trouble and special order the highly rated clutch master cylinder.

      Comments about CARQUEST Clutch TECHnovation Clutch Master Cylinder:

      Spent 4hrs replacing my master cylinder, start to finish from removing the clutch pedal to bleeding the system, I couldnt understand why i had been through 3/4 of a large bottle of brake fluid and it still wouldnt stop producing bubbles in my bleeder kit line. Kept finding brake fluid underneath the master cylinder which i attributed to unsteady hands filling the resevior. Nope, it was the new master cylinder leaking, straight out of the box.
      Whatever you do, pay the extra. If that means getting OEM or higher quality from a parts store, then do that. I should have forked out the money for OEM, but Im cheap.

          • Q:

            After a few months installing this master cylinder, I found a leakage where the rubber hose connects to the master cylinder from the reservoir. Did I install it correctly? Are there any special instructions I should do before installing it? Thanks

              A:

              I would suggest taking your vehicle to a certified mechanic for a proper diagnosis that you have installed correctly and the reason for your leakage.

          • Q:

            where do you fill master cylinder up with hydrolic fluid? or if it was replaced and now the pedal goes to floor and it stays there until you pull it up with your hand did it break or is it something else

              A:

              There should a line that connects to the master cylinder that connects on the other end to a reservoir. This reservoir is where you add the hydraulic fluid.

            • A:

              that's exactly what happened to me and it's leaking by the master cylinder stem. It would retain the fluid for a while and the disappear suddenly. I'm replacing it today.

            • A:

              Im an ASE master tech. The master clutch needs to be bench bled before installing. If you dont know how to do this, youtube it or just take it to professional. The pedal going to the floor means it has air in it and will take lots of pumps back and forth to get the air out. Its a common mistake I myself have even made.
