Clutch Master Cylinder

Does anyone have an opinion about Exedy clutch master and slave cylinders? They are fairly inexpensive from RockAuto. Wondering about the quality.

I have not yet used them but if quality compares to their clutch kits I've used frequently I would give them a try.

I recently bought both from rockauto (not sure if they were the exedy brand) and was disappointed. I have an SA and the master was the wrong thread pitch, on both of them I had to chase the threads to clean the out in order to try and use them. I ended up just ordering the OEM units from Atkins which turned out really well. In the process I converted to using the FB master and also got the SS line and new hardline from them as well.

I will say for the price, the RA stuff is worth trying out because its so much cheaper. It depends on how much you value your time more than anything.

I have used Exedy clutches and been very happy.

As for the master cylinder I recommend staying away from Centric. The master I got from them (from Rock Auto) popped a seal during bleeding and the rear drums from centric were more out of round than my 33 year old OEM ones........

I too had issues with the thread pitch on the clutch master cylinder that I bought from Rock Auto. Not their fault though. The fault lies on company that manufactures the part for Exedy. I ended up pulling the guts from the master cylinder that I bought and honed my current master cylinder's bore and put the two together to make one. Worked perfectly but a rebuild kit would have been cheaper but I was out of time on the car so I had no choice.

the Centric drums I bought from RockAuto were out of round. What I saved on their purchase price , I spent on machining
