Hydraulic Release Bearing or Stock ZF Release

This is for those running a ZF. What would be a better way to go, a McCleod hydraulic release bearing or to use the standard ZF fork and an external slave cyliner?

Thanks

external Bill. Even though I am having trouble with the slave on mine, a new one was 30 dollars and took me 20 minutes to change. Working out the right slave to master sizes will help pedel pressure
 
I have a McLeod internal release bearing on my Pantera, and a Tilton unit in my 427 Cobra. For years Dennis Quella of Pantera Performance Center touted the virtues of these units, and I literally bought into them. I have had one failure with the Cobra, and none yet with the Pantera (after about 5000 miles), although stories of failures are rather common.

Were I to do it all over again, I would DEFINITELY opt for an external slave cylinder setup. The actual advantages of an internal unit seem to be minimal, while the liabilities are quite great. For ease of maintenance, and reliability, you can't beat the simple external setup. And when you factor in the high cost of the internal units, it's a no-brainer IMHO....
 
I am an internal guy. I have had great luck with the Mcloed set up. It is really easy and space is a premium. Be careful with pedal travel. To much and you will blow out the seals. They are not the simplest choice but I would not do it any other way. Just one man's opinion.
 
The hydraulic t/o bearing is good, the Tilton in my race car has been going for years, the Mcleod is a little different, I have run them in several cars and the most important thing is in the set up. You must have only enough travel to release the clutch. You must install a stop on the clutch pedal to limit the travel of the hydraulic t/o.
I have an external slave on my GT40, it works just fine and takes 10 minutes to replace, as opposed to dropping the front crossmember and removing the engine and trans on my Tiger to fix a leaking hydraulic t/o bearing.

I too have the Mcleod HTB unit on my Kirkham and it has been trouble free, however I would definitly opt for one of the new external units Kirkham is making now for all the reasons sited above. You know the HTB will fail at just the wrong time and instead of a 10 minute replacement it will be days and high dollar

Hey Bill,

A little late to the party but I went with the external as well. I like the concept of the internal but for all the reasons already outlined decided external made more sense from a practical standpoint.
