Does anyone know if there is any difference as far as pressure requirements of different style hyd master cylinders for GM clutch set ups?? I am putting a T5 trans in my 40 from a camaro and the master cylinder has an angled base where it bolts to the camaro firewall, I need a master with a flat base so it will mount to my (vertical) firewall and be straight......I have found a few on ebay from various GM products like full size trucks, any problems using one of these with the camaro slave?? Also, some of the masters have a different outlet location for the hose (line) than the camaro master, can I take the ends off my hose and purchase hose in bulk or by the foot and make my own line to the shape and length I need??.....The hose looks as though they are heated and pressed over the ends which I believe have barbed ends..... Anyone ever do any of this??
Sometimes is easier to go aftermarket. I used a small Wilwood master cylinder for my modified T project. Available in different bore sizes, mounting flange is square to the bore, and has a conventional inverted flare line port. Cheap, too. http://www.wilwood.com/Products/006-MasterCylinders/005-CSBMC/index.asp Bob
i'm not sure about this bulk hose and barb ends stuff you are talking about. you need to do the line for the hydraulic clutch just like you would brake lines...steel hard line properly mounted and then a flexible brake hose for some flex where needed.
The stock line does not have threaded ends like brake lines, the ends have O-rings and a roll pin to hold them in place...The hose is a moled plastic type hose simular to high pressure fuel lines on new EFI equiped cars... I don't think the master and slave can be drilled and tapped to put fittings in to adapt steel lines and threaded ends.. below are pics of what I have...
Somewhere around 98 camaro went to a braided clutch line with threaded ends. They're the hot pieces to work with for a retrofit because of the line issues you've discovered. Good luck
I believe in 98 or so they also went with a Hyd throwout bearing, I'd rather stay with a slave cylinder in the event of failure it will be easier to replace, with the hyd throwout bearing the trans has to come out, not an on the road fix...... Thanks for the info though...
I'm using a master cyl from an early 90's jeep cherokee on my F1. It mounts on a flat firewall and has a threaded hole for the hose. It's just a standard Girling cylinder with a circliped on pushrod which is easily modified to fit your pedals. I have the same camaro slave cylinder you have, with the same ends. A local bearing and hose supply house claims they can braze the end onto a standard fitting for a flex line. I'm going to try that unless something else comes along.
I also installed a Camaro 5 spd in my car, which is a 1947 Ford coupe. I tried to use as much of the Camaro clutch setup as I could, pretty much the same as it was in the Camaro, but the plastic hard line out of the master and down to the slave cylinder was stretched too tight. I ended up getting a master cylinder setup for a corvette which had a much longer braided stainless line. It allowed me to use the Camaro clutch stuff and make all the connections without any problems at all. It bolted in without modification. Don't know if this would help you or not?
FWIW, I recently researched and bought a Wilwood universal hydraulic clutch pedal assembly for my hot rod. They claim all clutch slaves/throwouts are very close in terms of hydraulic requirements and their 3/4 bore master cylinder works just fine with all of em. Now, this is just Wilwood's claim, I'm not on the road to verify it. But what I do know from my OT cars, you can mix and match every OEM hydraulic clutch component on Chevy V8s. Truck, corvette, camaro. As long as you can make a line to connect the master and slave, it works fine. Personally, I'm not afraid of hydraulic throwout bearings. They've proven very reliable in OEM apps and make for a cleaner install. Have had far more trouble with forks and pivot balls. Good luck
I have used a master from 86 ford pickup ,it mounts flat. The line will fit in it also,unless you have a length problem. If you do you can splice hoses with a compression fitting as long you install steel sleeves inside the line.
I used that exact setup you have pictured, mine came out of a S-10. I used all of the factory stuff to keep costs down. If memory recalls I fabbed my pedal assembly bracket where the m/c would mount at that angle. It all fit behind the firewall behind the dash. I even used the remote resevior mounted up above the steering column. The only problem I encountered was that the "hard" plastic line didn't bend quite the way I would of liked. I took a propane torch and LIGHTLY heated up the empty line and bent it to the way i wanted it bent. This setup was for a t-5 behind a flathead, it worked extremely well.
I used the GM truck system on my Mustang. It bolts flat to firewall. I pulled the roll pins and cut away plastic lines. I then brazed steel brake line in place of it and shaped it as required to fit my T-5 into 69 Mustang. I built a bracket for slave to bolt onto bell and it works perfect now for 5 years. Go for it!!
I also used a clutch master cylinder from a 80's JEEP along with the matching brake/clutch pedals. I modified the OEM S-10 slave to fit my needs, but they do sell adapters that go onto the slave (with the roll pin retainer and -3 AN fitting, Russell #640281) that allow you to run a braided hose up to the master. I haven't used them but I beleive these are correct for GM and are available from Summit.
Thanks everyone for all the help and info, you have given me a lot of ideas on what to look for to set this up.. I have to get some measurements on my car and do some bone yarding to see if I can find a pedal assembly that will come close top working or one for parts and make up the bracketry to hold the pedals...As I get this part of the project under way I'll post some progress pics... Thanks again
the search function works very well! thank you,, but this is an old thread(4 years old) and wondering if there are any new ideas.. i am doing the same as the original poster.(camaro wc T5 using all the stock hydraulics) i have a 90's model truck master that i think i can splice in, to, but just wondering if there is something else that people are using more of now(off the shelf) thanks
