Hello there I have a 1962 Bently S-3 and i am wondering what is the exact correct procedure for bleeding the system out? I also noticed that on each wheel there are 2 bleed screws, one at the top of the drum and one at the bottom of the drum, does anyone out there know what the bottom bleed screw is for???

Don't know the exact car which somewhat predates my tech school stuff but think! Air rises and this may use two wheel cylinders so bottom one first and the one furthest from the master cyl. Just know that when a master cylinder is first pushed to the floor it can go into crusty territory and wreck the master that wasn't the issue to begin with!

If this is right or left hand drive the order would be to do the longest line first in either case,

Mikey; This, more than likely, has two wheel cylinders per wheel. My '40 Ford Coupe had two cylinders, also. Bleed the lower ones first, then the upper ones. Removing a brake drum should help understanding the setup.

Hi Loren, one of the other techs had bled the top out first so now i have to get the bottom to bleed out so i can redue the entire procedure. do you know if there is another way of bleeding other than either gravity bleed or do u recommend having one person inside while pushin the pedal? because i have opened the bottom up but now no fluid flows out so i have to get the fluid to flow first, Thankyou for ur insight

Vacuum bleeding works good & is easy on the system especially if you didn't replace the Master. A little teflon tape around the bleeder screw threads helps keep it from sucking air & gives you a good solid stream in the hose.......

Mikey; I forgot to mention starting at the wheel furthest from the master; RR, LR, RF, LF in that order. You want to be very careful when bleeding if using the brake pedal. If the brake pedal is pushed beyond it's normal stroke, you can very easily rupture the primary or secondary cups in the master cylinder. Although it is a slow process, you can use a vacuum pump to get the fluid to start flowing, then use gravity from there. Not sure the configuration of the master cylinder, but if you could get an adapter to fit, pressure bleeding is the best, and quickest, way to bleed brakes.
Also, when the bleeder valve is open, lightly tap on the cylinder to draw any air bubbles towards it. Be patient, allow it to bleed for a while, watching the master and keeping it full.
