Who is using an under cab master cylinder and brake booster?
I have seen these in alot of catalogs and I am considering it but I want to get some feedback first. Maybe something on ease of install, what do you have to do to add brake fluid, if you had it to do again would you, you know the normal thing.

I have one on my 56 F100. It's from CPP. Disc up front MII and Drum 9" in rear. Ease of installation = easy. Difficult to check and add fluid as it is underneath the cab and res is close to floor. I use a syrenge with a flexible hose on the end to add fluid. I read where someone adhered a small mirror to the underneath of the floor to be able to check level. I do like it out of sight. Prolly a personal preference thing.

Hi thendrix
I have the TCI (Total Cost Involved) setup for my truck. It bolts to the inside of a boxing plate using existing mounting holes for the front running board bracket and front cab mount support. You will no longer be able to use the stock clutch linkage with this setup. This is not an issue if you are planning to install an automatic transmition. I am using a T5 5 speed with a hydraulic clutch. There are adapter kits available to mount a vacuum booster and duel master cylinder retaining your stock brake and clutch pedal brackets.
These modifications will both move the master cylinder significantly back. It will now be under the seat. I plan on using a mirror to check the fluid level. You could also relocate the access hole to under the seat.

I installed the kit from CPP. It was fairly easy to install. I cut a hole in my floor to access the reservoir. The hole goes right through the large strengthening rib that goes across the width of the cab. It made the floor very flexible and cracks/tears began to form at the corners of the hole. I later strengthened the floor with some angle steel and some straps welded across the floor. Even with the access hole, its a pain to fill since its right under the middle of the seat. If I had to do it again, I would still use the kit, but I would mount a reservoir remotely under the stock location.
But, having said that about the install, I really don't like the feel of the pedal. I run the m/c and booster with disks up front and drums in the rear. If you even slightly touch the pedal you're going to stop on a dime. Way to sensitive for my tastes, and a huge change from the stock brakes. I've contemplated plugging the vaccuum line on the booster and running it that way for awhile, but I haven't gotten around to it.

It all depends on what the Year of your truck is on how hard it is to mount & maintain it & you've yet to state the year of your truck.
Because different years mounted them differently & had different ways in which to access them, as '57-'60 & later model trucks are easier to maintain w/ this particular P/B system & the earlier models are more difficult in others opinions.

Sorry Col. I have a 49 F1. I have also seen in the cpp catalog that they have some kind of kit or adaptor that is needed on the 53 - 56 trucks to use the stock clutch setup. Is this needed for the 48 - 52 as well and if not what are the diffrences in the two? I ask because I hve never seen a clutch linkage from a 53 - 56 and I just wander what changed if anything.

Mine is from CPP as well. Power booster and dual resivour master cylinder. Easy to install. I am running stock drum brakes front and rear still.
As far as checking and filling the fluid. I have a piece of polished aluminum that will be glued to the underside of the floorboard when it gets painted. For now..I just hold it over as a mirror. I fill it with an oil squirt can. So far....(since july of 07) I have never had to add any fluid.
I do check the level before long trips and occasionally at other times. Much like any modern vehicle.
