Type-45 master cylinder access

Recommended Posts

Has anyone out there made a modification to the floor to allow easier checking of brake fluid? I'm thinking of cutting a hole and fitting some sort of access hatch or plug so that the fluid level can be checked without removing the floor, or my current method of choice- reach up from under the truck and stick my finger in the reservoir (does this make me a human dip-stick?).  Some may view this as a sacrilegious move, but I'm trying to remove barriers to safe operation in hopes that this rig will be cared for and operated into the future.

I've done the same thing.  It made checking the fluid level a breeze.

my LS85 has a small reservoir (about 1/2 qt) under  the seat with a line tapped into the cap on top of the master.( wish it had air brakes)

Sorry, no pictures.  I don't even own that truck anymore.

Here is a drawing of what it looked like.  Made a metal circle larger than the access hole.  Bent a couple of tabs down the same diameter of the access hole.  The tabs and the weight of the floor mat kept it from moving around.

Being that yours is a fire rig with probably no floor mat, I would use a piece of metal held in with a couple of screws or Dzus fasteners that could be obtained through a local hot rod shop or Summit Racing.  See link.

A couple of minutes messing with the screws or Dzus fasteners is better than going under the truck to check the cylinder.

I seem to agree with j hancock...... go through ,may be easier to make a square hole instead of round

Not sacreligious if it is done in the name of safety. ease of preventive maintenance and does not greatly alter the overall appearance of the vehicle.

B Models with Juice brakes have a round hole about 4"' in diameter  locatedunder the drivers seat. Uses 2 screws to hold it down. 1 screw comes loose to rotate it out of the way to check the master cylinder.

I had the same problem with my 52 Type 75A. I added a remote tank under the passenger seat that is plumbed to a replacement cap that I threaded a hose barb into. Here is a link to the tank: https://www.amazon.com/dp/B002G35Q3U/?coliid=I1ZCP2O7IVJ7A9&colid=K1HH1OB1LY8D&psc=1&ref_=lv_ov_lig_dp_it
