WilwoodMaster Cylinder, Compact, 7/8 in Bore, 1.120 in Stroke, Direct or Remote Reservoir, Aluminum, Black Paint, Kit

I bought 3 of these to go with my Wilwood pedal assembly. I have them installed, but have not driven it yet

Pros: I used this to replace the Wilwood master cylinder on my hydraulic clutch system. IT was easy to install.Cons: Wilwood calls this a short cylinder but while it may be shorter than some others they make it is not short. And, the fact that the output fitting is on the end makes the entire assembly even longer when installed. As always with Wilwood and other manufacturers' cylinders I had trouble getting the system bled and pedal adjusted. In fact it still needs more adjustment to get it to act like a factory hydraulic clutch. In order to get a reasonable pedal height and free play and still release the clutch before the pedal hits floor the cylinder is at least 20 to 30 percent of its travel when fully released. Note that it may be possible the release bearing has too much clearance but the transmission must be removed to check and adjust this.Installed in 1966 Pontiac LeMans with a Hydromax hydraulic release bearing. Cylinder is horizontal and pedal ratio, etc. is as recommended by Wilwood.

Looks like a well made clutch master cylinder. Used it on my Datsun 240z but something to note if you are using this on a Datsun 240z know that the dust boot won't fit through the firewall and the boot will have to be installed from the other side. Easy to do if thr dash is out but if not you better be limber enough to install that dust boot under the dash.But as the title says on my review "Missing major part", it was missing the large reservoir, had to return it and reorder it again. Second one was complete. I don't know if I got an item that was returned or missed packaging inspection.All in all I'm pretty happy with the product itself.

use this for my 1970 Mustang T/A racecar

This is the smallest bore diameter in this style and it has enough volume to move Porsche 996 turbo calipers if anyone is wondering.

I installed this a few months ago and haven’t had any more issues with my clutch master going out. I needed a larger bore cylinder and this worked perfectly. I had to get a plate to mount it to the firewall properly but it functions great! Thank you.

As with most Wilwood products, no disappointments. Great quality and everything you need in one kit.
