Yes, the very failures your describing and which have plague all of the VQ cars equipped with Nissan Concentric Slave Cylinders is greatly reduced with the RJM pedal. The reason for this is simply that by reducing the excess pedal stroke and deadzone where the pedal/CSC continues to stroke past where the clutch is fully disengaged it reduces the wear/tear that accumulates with every shift. With the factory pedal the CSC piston is travelling in its bore about 50% more than it needs to in order to fully disengage the clutch so that extra travel on each shift wears the seals out faster. Reducing the stroke reduces seal wear. Secondly the main reason for sudden CSC failure is “popping” the seals when the piston travels too far and blows out of its housing. Again this is caused by excess fluid being forced to the CSC from the master cylinder and reducing the master cylinder stroke (thru AFP setting and pedal height) reduces the total stroke of the master cylinder so it pushes a lesser volume of fluid to the CSC on each pedal stroke greatly reducing the chance of blowing out the seals.

The factory pedal with all its excess stroke runs right on the ragged edge of popping these seals with every pedal press and the sheer number of owners who’ve experienced repeated CSC failures demonstrates this. There are a combination of factors that can lead to CSC failure with the stock pedal but it’s possible thru a combination of rapid expansion of the clutch the fluid from heating while driving hard to build some extra pressure in the clutch line and if the balance valve in master cylinder doesn’t allow the expanding fluid to flow back to the reservoir then on the next full pedal press the CSC can overstroke instantly popping the seals.

With the RJM I won’t say the CSC can’t fail as I’m sure eventually all CSC’s will wear out from old age and high miles however with the CSC only stroking about 50% it’s useful life span could be as much as doubled by reducing strain to the seals which are the weak link in all CSC’s. To date in over 3 years of selling these I’ve not had a single customer report any sort of CSC failure after the install of my product and none have needed warranty work due to said problem. One customer with a modified clutch told me he’d popped 2 or 3 factory CSC’s in a row before buying the RJM pedal and has since been failure free for about 2 years now.

As well I’ve had a number of customers report having their cars in for major warranty service work and the dealership either didn’t notice or didn’t care as they never mentioned it to them and full coverage was applied. If you’re worried about the possibility of a denied warranty claim in future for a transmission related issue to be 100% safe you can swap the factory pedal back in before it goes to the dealership in about the same time as the initial install and they would never be able to tell the RJM was there since nothing is permanently modified during installation. It would be a little of your time to swap them but you’d be sure to get full service. As well by law they can’t deny warranty service for mods which can’t be directly proven to have caused the problem. Example a blown engine can’t be denied because of a clutch pedal or suspension upgrades, etc.

Hope that helps a little in putting your mind at ease over your warranty coverage.
