Update: July 2022
This LuK hydraulic master cylinder lasted just over 11 months before failing. Since it is aluminum, it did not split like the plastic versions. Instead, fluid was leaking past the piston. It is no longer holding pressure when pressing down on the clutch pedal.
I went looking for yet another aluminum body clutch master cylinder. I compared a direct replacement LuK LMC129, a new version LuK (listed under the same part number LMC129), and a Dorman CM126856.
The ‘original’ LuK is bare aluminum. The ‘updated’ version has a gray-green coating.
Out of the three, only the updated LuK had the correct length push rod. In my earlier review (below) I stated that I had to cut a spacer for the first LuK as the push rod came up about 1/8″~3/16″ shy. The updated LuK push rod length is equal to the old push rod plus spacer. The Dorman push rod was also too short, equal in length to that of the first LuK push rod.
The updated LuK master cylinder and Dorman master cylinder were pretty much identical. They must had been made by the same manufacturer. The push rods were made differently. Both of these cylinders have a gray-greenish coating. The original LuK and direct replacement LuK have a bare aluminum finish, no coating.
The updated LuK is the one I went with. Hopefully the updated version with the correct length push rod lasts more than a year; several years would be appreciated. I’ve become too good at messing with this darn thing. This is due to going through so many different parts in hopes of finding a quality one.
Best of luck.
Original Review, July 2021:
1995 Chevrolet K3500 6.5TD 4×4 Crew Cab Long Bed Dually.
Like many GM truck owners with a NV4500, I’ve had my share of problems with the cheaply made hydraulic clutch PLASTIC master cylinders. I was extremely happy to find this metal (aluminum) body offering from LuK. This is the first LuK product I have purchased and had no idea what to expect quality wise.
Out of the box this master cylinder appears to be very well made. The casting is clean with minimal molding lines. The machined surface appear to be well cut. Over-all it looks and feels like a quality product.
The master cylinders I have had in the past have a clip on the end of the push rod that snaps into the end of the piston, positively retaining it in place. The LuK version does not. Instead, the push rod ‘floats’ or just sits in the end of the piston.
I installed this master cylinder and followed the typical bleeding procedure. I’ve done this a few times over the years with success and understand what I am doing; not a professional mechanic but have experience with this job. After a great deal of effort and time purging the system of air, the pedal feels firm with no sponge, but the (one year old) clutch still would not fully release.
I unbolted the master cylinder from the firewall and measured from the center of the clutch pedal pivot point to the mounting surface of the master cylinder. It comes up 1/8″ shy in comparison to the GM OEM plastic unit it is replacing (a plastic NOS unit I installed last time around that eventually failed too). As a test I cut a 3/16″ shim and placed it between the push rod and the piston. The piston has a machined recess (hole) in the end that the push rod rides in, plenty deep to accommodate the test shim. With this shim in place there is no ‘pre-travel’ of the clutch fork, and the clutch now fully releases.
This morning I called LuK and spoke with someone who was knowledgeable about this master cylinder model. I was hoping to find a spec for the push rod length to compare the one I received to in hopes of determining if I received the 1 out of 10,000 that is a lemon, or if it is a flaw in the design. Unfortunately he did not have push rod length specifications or how deep the recess in the end of the piston should be.
I am going to roll with the test shim for a few days and see how it performs. If everything appears fine I’ll cut a new, permanent shim and install it.
Quality replacement parts for our OBS Chevrolet and GMC trucks should not be this difficult to find. But, the flood of cheap parts from overseas makes it a multi-week chore of trial-and-error for the DIYer to find quality parts and keep their rig on the road. I am hoping for the best with this LuK aluminum body clutch master cylinder as the quality of the part seems high. It is unfortunate that I’ve come across this problem. The high failure rate of plastic master cylinders makes measuring and cutting shims an unfortunately reality.
My truck came equipped from the factory with the NV4500 and the one in there now is original to the vehicle. The previous owner pulled a large trailer and replaced the clutch once when he owned it. I’ve owned my truck for 14 years now and had the clutch replaced some 15 months ago by a local transmission shop. Other then the previous owner replacing the dual-mass flywheel with a one-piece unit, my truck is unaltered. I am confident that there is no air trapped in the system. All signs, to include measuring with a ruler, point to the push rod being shorter than what is called for. If not for this issue, I would initially give this LuK aluminum body master cylinder five stars.

Was hoping it was a long lasting unit from what I read. It lasted a few months and it’s already leaking into my carpet. Cheap seals from China. Avoid.
Jeffrey Dean –
Didn’t even last through bleeding it and the seals would already not hold pressure. Recommend any other brand.

Excelente
Jeffrey & Kally –
As soon as I installed and pressed the clutch in, the rod bent, which rendered the master cylinder useless, and the time i spent installing it, a huge waste.

Worked on my 95’ Chevy 2500

This was absolute garbage, had to be replaced after two weeks of use. Part failed. Created a very dangerous situation.
