Pacifica Pete Posted August 29, 2019 Share Posted August 29, 2019 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. -Pete Quote Link to comment https://www.bigmacktrucks.com/topic/58822-type-45-master-cylinder-access/ Share on other sites More sharing options...
j hancock Posted August 29, 2019 Share Posted August 29, 2019 I've done the same thing. It made checking the fluid level a breeze. Quote JimIt doesn't cost anything to pay attention.

609albert Posted August 30, 2019 Share Posted August 30, 2019 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) Quote Link to comment https://www.bigmacktrucks.com/topic/58822-type-45-master-cylinder-access/#findComment-431101 Share on other sites More sharing options...

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. https://www.southco.com/en-us/product/hierarchy.html?hid=7345 1 Quote JimIt doesn't cost anything to pay attention.

609albert Posted August 31, 2019 Share Posted August 31, 2019 I seem to agree with j hancock...... go through ,may be easier to make a square hole instead of round Quote Link to comment https://www.bigmacktrucks.com/topic/58822-type-45-master-cylinder-access/#findComment-431180 Share on other sites More sharing options...
1958 F.W.D. Posted September 1, 2019 Share Posted September 1, 2019 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. 1 Quote TWO STROKES ARE FOR GARDEN TOOLS Link to comment https://www.bigmacktrucks.com/topic/58822-type-45-master-cylinder-access/#findComment-431228 Share on other sites More sharing options...
Firemack Posted September 12, 2019 Share Posted September 12, 2019 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.

fxfymn Posted September 17, 2019 Share Posted September 17, 2019 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. 1 Quote Money, sex, and fire; everybody thinks everyone else is getting more than they are!

1958 F.W.D. Posted September 23, 2019 Share Posted September 23, 2019 CARL!!! Haven't seen you on here in quite a while!! Hope all is well! The boys and I ended up camping in Gettysburg again, and went to four different battlefield walks. We had a great time, too. Maybe next summer we can branch out to a different battlefield!
