67 drum woes
I have a 1967 1/2 ton with drums all the way around. We put a power brake setup from a 1972 chevy on it. Everything worked great. I took it to my uncle in law's shop to have break shoes put on it (I know do it yourself and you won't have these issues, I got lazy ok) and he took it upon himself to fix my now faulty booster with a 1970. Well this caused all kinds of issues including the brake rod was too short and the vehicle was pulling to right severely. We fixed the rod issue buy welding two together. What I am wondering is could that 1970 booster actually cause the pulling or is it just a coincidence? I have replaced all the wheel cylinders, brake shoes, brake lines up front, master cylinder, and took off the distribution block/proportioning valve to check for any stoppages. I don't really want to spend the money on a new booster since this one cost 100 plus and I will have to buy the rod too but, I don't really see what else could be causing this. Does anyone have any ideas? Any help would be appreciated, thanks.

Re: 67 drum woes
thebooster will do nothing from left to right... odds are, it was the brake job.
My guess without looking, whomever installed the shoes, put the 2 long shoes on one side, the the 2 short ones on the other side, instead of long/short on both sides. |

Re: 67 drum woes
Thanks for the advice guys, I think you got me goin in the right direction. I checked and it doesn't have 2 shorts on one side and 2 longs on the other but it does have them reversed on the right side. I will change them tommorrow and hope it fixes my problem. Thanks again.

Re: 67 drum woes
Here's what I've experienced on my 2 drum brake trucks.
Depending on the quality of the new brakes and condition of the drums themselves, I've had to readjust several times after a brake job to get them right. And even then, they still tend to pull slightly to one side or the other. I'll drive them for some time and then come back and readjust. I've never been able to get them perfect. Close, but not perfect... The only way you can get them pretty close after a new brake job is to take it in to a brake specialist shop and have them redo the drums and then the shoes to match the curvature. |

Re: 67 drum woes
he found the problem, they were installed wrong
there should be no reason you can't adjust them properly if your components are good. |
