has anyone adapted a Mcleod master cylinder to their third gen? i'm switching to a hydraulics throwout bearing and i'm getting a mcleod kit.. comes with practically everything.. the only problem is that i have to adapt the master cylinder to the firewall.. anyone on here do it before?

MrDude_1

it mounts just like a stock 4thgen one...
and the 4thgen one mounts on the firewall like the 3rdgen one.

mine just bolted in place of the T56 one i already had in there.

5678TA

no no no, the one that comes with the kit is different.. heres a look.. the first one is the stock style, which i'm NOT using.. the second picture is the kit i'm getting.. see how the master cylinder is made? it has a level shaft..

MrDude_1

you'll be cutting some and making a bracket then..

theres just enough room in that area... you may end up with a diff reservoir

i see.. its gonna be an interesting project, thats for sure.. hopefully its worth all the hassle.. cause the stock hydros are killing me..

Man that looks like it's going to be a major pain in the *** to do, I don't get what's so bad about the stock setup? If you need more flow between the slave and the master out of the stock one you can drill out the restrictors in the line.

MrDude_1

yea... if it was me, id "mod" the normal mccord aftermarket one by replacing the custom GM connector banjo fitting on the end, with a AN banjo.... then you can make a line that works with whatever.

I am almost to that point. Once I get the underside of my car finished up I will be working on exactly what your talking about. In looking at it just as a glance. I am planning on welding up a part onto the clutch pedal inside of the car. Then mounting the clutch master cyl onto the firewall to the outside of the brake master cyl. It looks as it is going to be a pretty easy task to make the part for inside of the car. When I had my full length headers built I told them not to worry about clutch linkage. My 82 had that crappy designed 3 peice z-bar cross shaft for the clutch. I'll put up some pictures when I get to that point. If you have any questions you can always PM me.

yea, I have that crappy Z bar setup, and from what i've heard its... crappy. I have no idea what the alternative is though, so lets see what you come up with

UnstableAviator

I've got a Tilton 1" master cylinder in my car, which looks almost exactly like the one you pictured.

Use the external mount resevior, only because you're not gonna have room under the brake booster to anything else. I monted mine in the upper left corner of the firewall. (driver's side)

As for the bracket, a relatively simple sheetmetal piece with a little welding will to the job. I'll try to sketch one out using MS paint, but don't expect a perfect CAD drawing or anything.

Done correctly, the bracket should bolt in and hold the master cylinder in place, but allow for easy removal and no modifications to the car. You'll find its a very tight fit to get the angle correct due to interference with the front sheetmetal "frame", but even if the angle between the pushrod and cylinder isn't perfect it will work without a problem. Be sure to make a strong pushrod to link the pedal to the cylinder; I had trouble with mine bending until I went crazy and made one totally overkill. I hope the cheesy diagram helps, hopefully it will give you an idea of how to make it work. If you need actual pics, next week when I'm off work I'll go take some digital pics of my "in car" setup. Good luck.

Actually I wouldn't buy that kit. I would call Mcleod and dial extension 230. Ask for Bernie, he's the head of the hydraulics dept. He'll be able to give you exact PN#'s for your specific application.

Yep, Bernie knows his stuff... he gave me all the correct part numbers to get the install right the first time. He is a busy guy so it might take you a while to get through to him. FYI, I did my T-56 install using the master from the first picture.... farily simple, mounts like the stock piece... not sure why anyone would do it a different way. I used a thirdgen peddle assembly and had to make a couple modifications to get the rod end on the slave to bolt up but it was pretty simple.

fenton06

is there a place that you bought your pedal assembly from, or did you just scavenge them.

If i wanted to buy a new pedal assembly...where would I look?

RWB____s

I have the Mcleod unit in my car. It just bolted right in with no problems. Ran the hydraulic line down to the slave and pluged it in. I am using the stock resevoir also.

5678TA

what exactly do you have in your car?? McLeod master? hydro bearing? both?

Dan W

I swapped with a friend who was going automatic. Otherwise, I'd look for a set in a U-Pull-it yourself Junk yard as they have the best deals. Check the classifieds here or use one of the sites sponsors.
