Type Iii Rear Brakes
« on: January 05, 2006, 02:15:54 PM »
What year should I be looking for to fit wide 5 type III rear brakes to my 69'IRS pan? I have heard that I need the parts from the backing plate out from a 65' square or notch. Yes ? no?
Not a whole lot to pick from in my area anymore since they crushed everything under 1990 at the junkyard.

Any of the rear backing plates from 65-73 will work. If you want 5 bolt drums then you need the 65-66 drums or four bolt are 67-73. Notch, fast, square or T34 are all the same.

Geoff, don't you mean 64-65 drums?
In  66 the T3's went to 4 lug.

So the only thing I need to source is the backing plate (with levers etc) and the bearing flange and  the rest I can buy off the shelf right???

my type 3 bearing flanges did not fit my axles tubes i had to use the one's that were meant for the axle tubes(if that makes any sense)

If you can find brake parts for them. 62/63 T3 brakes are 2 year only.

Hey Guys,
correct me if i am wrong, but i am pretty sure that the early t3 brakes (62-63 ) are NOT the brakes you are looking for, for the big brake conversion.  Those brakes aren't much bigger (if any) from an early set of bug brakes.  For the big brake conversion, as Geoff mentioned, you need the 64-65 rear backing plates for 5 bolt, or the 66 and later for the 4 bolt conversion.  The parts that you need, that you can't buy new, are the backing plates, the e-brake levers (i think) and i had troubles with the new brake shoe retaining hardware, such that i needed to find used pieces.  To source these parts, start by asking Airspeed, otherwise talk with Anthony at ISP West, he hooked me up and new exactly what i needed.

If you are looking to do the T3 big brake conversion on a earlier bug that has the short axles, you must also machine off part of the brake drum (the outer most \"nipple\" where the axle bolt touches the drum).   You end up machining off between 1/2\" to 5/8\" (argued).

You want to do Wide-5 bigger brakes on an IRS rear?
Why not just source out some THING rear brakes or better yet get the whole trailing arms and all. Having never done it I'm not sure what differences there are or what has to be modified but it sounds good in theory.

The car is a 61' on an IRS pan, I want to maintain the wide 5 and stock wheels with hub caps.
Thing brake drums can be swapped to the IRS rears but the type III brakes are larger(both piston and pad).
