Camaro LT5

[Stielow]

Because the DSE kit is based around a 4th gen Camaro master. I just copy the 4th Gen Camaro clutch pedal geometry. I purchased a stock 1992 Camaro Clutch pedal along time before all these stuff was available so I just use it as a template.

Here is the 69 vs 1991 pedal.

I weld on a tab to pick up the end of the clutch master cylinder. I drilled a hole in the stock pivot point on the 1991 pedal. I use a transfer punch to locate the new location on the 69 pedal.

I then drill and tab the new tab 1/4 - 20.

I used to use the stock 4 th gen GM master cylinders then they got fairly expensive and they were plastic. I found this part on Summit Racing web site and it is aluminum.

If you carefully remove the stock end that designed to hook to the stock 4th Gen Camaro pedal the Dorman part has 1/4 - 20 treads. I run a die down those threads after I remove the crimes on part.

I then use a piece of 5/16 thick wall tubing to make a new rod. Drill and tap one end 1/4 - 20 and the other end 1/4 - 28 for a 1/4 rod end

Sorry got ahead of myself a bit. Need to set the length of the rod prior to cutting it.

I mock it up on my table to sort that out.

Copying the stock 4th gen geometry should make the linkage at a 90 degree angle at 1/2 stroke. It you draw a line from the pivot point of the pedal to the pivot point of the rod end the to the center of the master cylinder it should be 90 degrees. This keeps the side load on the master cylinder to a minimum. If you are failing master cylinders most likely your geometry it incorrect and your side loading the master cylinder.

While you have the assembly out of the car and on the work bench also verify the push rod is straight. The centerline of the master cylinder and the push rod should be straight at half stroke. In my setup I had to add two washers to straighten it up.

I later tack welded the washers on the pedal to make it easier to assemble later.

I had to clearance the support to clear my bolts.

I use a long stud to make assembling all this in the car easier.

Because the LT5 ECM is looking for a clutch switch and I’m adding Cruise control I added a clutch switch also while I was making stuff.



My disclaimer. This works for me and there maybe other ways to do it. I have used this system on the last 5 Camaros with zero issues. I then to revert back to “what do GM do” for a lot of my solutions.

It is amazing the the 1969 clutch pedal and the 1991 pedal are the same length. These setup coupled with a Centerforce clutch make the clutch pedal feel like a stock Camaro.

Sorry one more thing. I add an adaptor to the Dorman Master Cylinder to convert to -4 AN line. Make hooking up the clutch easier. You can just purchase a premade line to fit. I do add a dry break so if I do need to pull the transmission I don’t have to re bleed the system.

When I took the Impala Convert I bought apart...…. Here's what I found for brake pedal linkage...….. LOL...… Pretty scary....
