Hydroboost Adjustable Push Rod Solutions?

[Yukon 400]

For those who have installed hydroboost brakes, I was wondering if anyone used units from an 88+ that had the fixed length push rod, and which method they got around the difference in length compared to the original bracket.

I was thinking about cutting the rod off where the body is straight, then cutting threads in and installing one of these threaded rod adjusters with a threaded clevis rod end.

I just wanted to see what kind of solutions have been derived for those who have already installed a hydrobooster setup, as I know that hydroboost is sensitive to push rod length and pedal travel do having adjustment will help in the initial setup.

Thanks,

The way you described what you are planning is the way I did mine, except I didn't use that style of clevis, I used the original piece that was on the original rod that went to the master cylinder. Hydroboost works great, much better than a vacuum booster in my opinion.

I know this thread is a little old but I figured someone might be interested in how it looks when it's done. I couldn't find a threaded adapter like you have pictured so I made my own. I used a 7/16x20 coupling nut and a length of rod threaded in 7/16x20. The original end of the hydroboost rod was cut off and the coupling nut welded into place. The rod was cut to length so my original 68' rod end would reach the pedal.

Something to keep in mind, the stock mounting point on the pedal might not be right for a newer style brake system. You need to make sure you're getting the right amount of movement for the master cylinder you're using. I'm useing a hydroboost from a 84 chevy truck with a diesel. I was able to just add a little material on the back of my pedal, and move my mount hole down a little. And I was able to move my peddle a little bit closer to the floor for more leg room.

I would be worried about the seal getting too hot when welding it, that's why I threaded mine and put c coupler on it. With something as important as brakes, I would want to be sure my weld was really hot to get good penetration.

I was initially concerned about the heat. The guy that welded it made sure to keep it under control. It helps that the rod is crimped in place and moves freely.

Hey woodwright, it looks like you mounted it directly on the firewall. I plan to mount mine with with Captainfabs booster bracket. I think that will help with the angle but I will keep it in mind.
