Chuck's Baja Build

....Does anyone see a with running the 10# valve, mounted between the MC and the turning brakes, even with disc brakes, (conversion)?

I'm very interested in this exact same issue. I currently have a stock (or near stock) VW master cylinder with drums up front and turning brakes and four-piston discs in the rear. My problem is that the first press of the brakes activates the sub-par FRONT drum brakes, the next pump on the brakes work great and the rear end squats down nicely. I had a 2lb residual valve installed immediately before the turning brake. Today I upped the residual valve to a 4lb unit and things got a tiny bit better. I asked the guy at Kartek about going with the 10lb residual valve before the turning brake for the rear and he said that that would be too much and my rear discs might never RELEASE. I'm *still* considering trying it though -- unless you beat me to it. So I'll be watching this post closely.

Very interesting! I agree with the "might never release" part and that is the point I wasn't 100% sure of but I hinted at.

As I think, I said before, for a single chambered MC I think there should be a Tee that separates the front and rear brakes similar to how a dual chambered MC does. The brake fluid is displaced by the MC application then the fluid goes either to the front brakes or rear brakes separately for application but still working as one system.

A stock type 1 has one in the left rear of the pan combining the right and left hand rear brakes lines together as a single unit. The use of the turning brakes eliminates the use of this Tee so you use two of the right side connectors, one for each side.

This picture shows both types of Tees the VW type 1 uses but in a bit different applications. The Tee that has the sender is a different application as there is similar application on each side of the brake system. What this does is it allows the brake light application for the side the handle is pulled on or when the foot brakes to be applied then both brake lights come on.

The other Tee is for the hydraulic clutch application.

Using a Tee just off the MC allows the 10# residual pressure valve to be for the front drum brakes only and the 2#/4# valve at the rear disc brakes via. the turning brakes. Remember, the discs don't have springs like the "can"/drum brakes have that pull the shoes back from the drums after each application of the brakes there by displacing some of the brake fluid in the slave cylinder back into the brake line but not too much of it (the 10#s limitation).

(Kind of off-topic) Years ago I saw an odd application where there was a single handle hydraulic brake that was attached to only the front brakes. It was in a Tow'd that the guy used for more slow speed off-roading/hill climbing. When he stopped on a hill he would apply the brakes then he pulled the handle locking the front brakes this would allow him to use the brake foot to then work the clutch allowing him to keep the vehicle from rolling back before the clutch disc was fully applied.

There are a lot of things that can be done if one thinks about it.

This one was so nice I found it hard to believe that he has ever gotten it dirty.

Yes, wish I had a pic of some of those back ends.

I guess that's the difference between you and me David. I am more of a breast man (I guess). I just looked at all the pictures I took that day and almost all of them are from the front.

A chance to get out of the house and visit the desert. It is so nice to have Superstition right out my backdoor. Nice little cruise. I did manage to accidentally find the only mud puddle in the whole desert. It was such a beautiful day and I got to spend it with my beautiful wife.

God for you, definitely jealous. See a lot of new territory?

Since my passenger is not really the adventurous type (I can count the number of times she has ridden in my bug in the ten years I have owned it on one hand), I kept my trail choices to the tame side. It was still fun bombing up the Choo-Choo road at 50 mph.

Yeah, but how was it driving the car?!

I am calling this, The Evolution of an Air Filtration System

In the beginning, I had a Baja running a 2.6 liter VW Type 4 engine with a single Weber 44 and my air filter looked like this:

Then came an update. I decided to upgrade to dual Weber 44s and my air filter system changed to this:

Air Filtration 1.jpg

This system looked very elegant and I was pleased with it's appearance. The only problem with this system was the carburetor "hats" were too small and restrictive and the engine did not want to run worth a darn. I was forced to go to Dual Carb version 2.0:

This version looked good, but I did not like the fact that the air cleaners were right down next to the rear wheels and after each run the filters were coated in dust and dirt. I was running Outerwears, but I was not that pleased.

Now I give to you Dual Carb Air Filter Version 3.0 for your inspection:

Appearance wise, this is not nearly as elegant as version 1.0, but I like that the air filters are tucked up high and inside the cabin away from a majority of dust that is kicked up by the back tires during my excursions into the desert. One negative is rear view vision is restricted slightly, but I have overcome that by installing a rear view back-up camera. I replaced the inside rearview mirror with the video screen for the camera. I have a lot better rear vision with this set up than I ever had with the rearview mirror.

I have a back up camera in my sandrail because I can't see past my radiator anymore. The only problem with it is that everything is backwards relative to the driver. Things in the mirror on my right side are actually on my left side.

For example, there are proper rear view mirrors available

My truck has a back up setup using a couple of cameras that has the rear of the car showing correctly.

I am going to be looking for one myself assuming I ever get my buggy done.

Wow! nice bug! I have been thinking a lot about air filters as the dust on the logging roads is thick these days. Great ideas I am seeing here.

She’s got some nice lungs on her Chuck.
