Technical floor mounted brake booster access panel ideas

Hello ,
I'm Thinking of putting a access panel for my floor mounted brake booster .My car is a 28 coupe .It has a metal floor what do you guys recommend that will be functional and looks good any ideas is appreciated..Pictures are helpful also .

 

Well depends....Depends on your tools and skill level. You can just cut piece of steel a little larger than the hole and screw it down or get a little fancier using a bead roller. My main consideration is to make the hole in the floor large enough for you to easily service the part. In a Model A that may be a difficult thing to do as there is usually not much floor space to work with.

I have attached some pictures of two covers I made for my coupe.
Original hole is way too small for the new tank and it's removable parts.

New tank

Cut with saws all on the straight cut and dremel tool cut off wheel on the corners.


I used a HF sheer to cut out the pieces and this bead roller to finish the edges and add a stiffening bead.

From below

Secured with self tapping screws.

This is the master cylinder location. New Mustang type cylinder is much longer than the stock one.

That red thing in the previous picture is a plastic jar cap used to mark the radius for the end cuts.

The bead roller was used to make the flanges and center bead.

Those tabs that were marked out in the first pictures were bent over to fill the void from the strengthening bead in the floor.

Secured with self tapping sheet metal screws. I used rubber gasket material to make a gasket around the edges of both covers.

These were really pretty simple to make and if you are not going to cover the floor with carpet would look ( I think) pretty much like a factory install. Hope this helps.

That is nice.

 

Here is the M/C access panel I put in my roadster, same idea would apply to a steel floor.
If you are going to use a rubber mat (my plan), or carpet, a simple flap laying over the cover should keep the lift off piece in place, no need to hinge it or screw it down.
Should stay (reasonably) dry unless you plan on running through high water.
In my case, with a ******* roadster in Oregon, there will be bigger issues than a little water seepage in the floor.

 

How about a cover from a small breaker panel?

 

How about the gas filler door from one of the new-fangled cars? You could remove the spring loaded cathch and replace with a magnetic type, or push-in click -out style.

 

Thank you all awesome ideas

 

I fabbed these using 304 stainless for the gas tank but the floor is fairly flat.
I dont have a pic of the brake booster door but I had a spare floor patch that I used to make a door frame and door...fits like a glove.

Unfortunate do not have you skill level or tools.It looks awesome by the way

 

That would work perfect

 

I have an underfloor booster in my project and made the filler reservoirs remote by mounting them in a toolbox and running hoses to the m/c.
in your case you could mount them in the trunk and run the appropriate rubber hose to the m/c...pretty simple

 

Saw these in Speedway's catalog: http://www.speedwaymotors.com/Master-Cylinder-Access-Door,51703.html.

Search access door on their site. They have a few options.

 

Since I am a talentless hack, I used a length of a glove compartment door hinge and a s**** piece of metal for the one I put in my Apache.

 

I used the step dies on the bead roller and recessed the floor pan, left the recessed flange and put a flat panel in (with a bead in it) for the cover. You can see it in the floor pan video we put together (jump to 8:11) .
Allows for a flush mount cover. I'm sure there are countless ways to do it, as long as it works!

 

Lots of cars had under floor brake boosters before the mid fifties. None of them had any access from above. They could only be serviced or repaired from below. Since they almost never require any, access was not needed.

You may be thinking of under floor master cylinders. They were also serviced from under the car, but had an access plate in the floor for checking and filling the brake fluid. Just a metal plate held down by 1 or 2 screws.

 

The access panel for the master cyl. in my roadster... from a P-51.

 

Here is the spare patch piece I had that I was talking about in my last post...formed a frame then welded the patch panel to the frame and mounted it with a piano hinge...no cost and turned out nice.
