Brake Booster

[btripp72]

I have replaced every single part of my drum brakes in my 69F100. They work great if I weighed another 100lbs. Any suggestions where to purchase a brake booster? Do I need anything else besides the booster?

Thanks!

There were a number of different boosters on the '67-'72 and '73-'79 model trucks. Not all Dentside ('73-'79) boosters are a direct swap to the '68-'72 model trucks, without out swapping to the Dentside pedal (s) and pedal hanger.

1967 is an odd - ball year and only a '67 specific booster will work with '67 specific pedal and hanger.

If you are pulling a booster from a wrecking yard donor truck, you'll need the booster (to turn in as a core for a newly rebuilt booster), the booster to firewall mounting brackets and the plastic boot that goes between the back of the booster to the hole on the engine side of the firewall.

Boosters will come in varying diameters and will either have a single-diaphragm or dual-diaphragm.

This is an 8-3/4" diameter Bendix dual-diaphragm booster I installed in my '69 F-100 Ranger, from a '75 F-350. --I swapped the donor booster for a newly rebuilt unit. The boosters input rod connected directly to the pin on my stock '69 brake pedal.

For the past couple of years, I've been running the booster with my stock 4 wheel drums.


Currently, I'm installing disc brakes on my '69 F-100 that I pulled from a '77 F-100.



I replaced my 'conventional' cast iron master cylinder with a modern MC.

Get a booster with an adjustable rod. U will aldo want the booster mounting brackets and the plastic boot to keep air coming through the firewall.

don't rule out your brakes still not working correctly, jack up each corner and make sure the brake is locking the wheel, make sure both sides of the cylinder are working, and make sure all the adjusters are snug. Make sure the brakes bed in properly and check them after a hundred miles to make sure the pads are making even contact.

my manual drums lock all four wheels pretty easily. unfortunately they lock the rear two slightly more easily than the front two.. ha! either way if your drums are good you shouldn't need too much force.


go for the booster by all means, just make sure you're not covering up a more serious problem.


if you don't mind paying the core charge on the booster you can buy one brand new, but you'll need to buy or fabricate the mounting brackets
