Re: [FWDLK] Total contact brakes



Sounds like the shoes make partial contact with the drum and wear down quickly. You need to perform a "Major Brake Adjustment". Consult pg 89 in your shop manual. I was lucky the last time I relined the brakes. They fit well without a "Major".

When doing a "Minor Brake Adjustment", the anchor cams at the bottom of the shoe should be adjusted until a slight drag is felt. This means the bottom of the shoe is touching the drum and a slight amount of lining will wear off quickly so the drum is free running. Then the wheel cylinder will push out the top of the shoe and total contact will result.

Sepatate note: modern linings are typically much harder than OEM linings. This is because almost all cars in the last few decades have power brakes with higher line pressures and linings need to be harder to last longer. The result in an older car with non-power brakes is less stopping power and higher pedal pressures. I installed OEM power brakes and problem solved. A lot of disk brakes conversions get installed for this reason.

 Total contact brakes, what year did they start and what year were they out?
I am having trouble on my 56 Dodge (may not be OE rear end) I cannot get the brakes right. it seems they work for a few times then they back off so I have a soft pedal….
I can pump them up but they are maxed out. and only the top part of the brake shoe contacts the drum. I cannot get the whole shoe to engage the drum….(drums and shoes are new and within factory spec…)
I am taking about the rears the fronts are disk and are now working great I had to add a bigger vacuum diaphragm booster, the rears are giving me the trouble. Is there a way to upgrade the rears in some way?
The parts all look new the wheel cylinders were just replaced. Is it possible not knowing for sure what year the rear brakes are is it possible I got 1956 wheel cylinders that fit fine but are too small for the set up? Thus not holding enough brake fluid?
 
What years of Mopar rear end interchange with the 56 Dodge?
