Wheel Alignment and Balancing

How or where can you have new rear brake drums balanced to eliminate severe vibration at highway speeds after rear brake job on your 95 Caravan Wheel balance was verified correct with spin balance?

It is true that some manufacturers balance brake components, but

most--especially price-point brands--do not. Poor casting technique

and even sloppy machining can result in a wildly imbalanced

component. If left unchecked, an imbalanced part can cause a

vibration that will rapidly wear components.

Consult your favorite business or phone directory for a few

local and reputable machine shops. Ask who they recommend for

balancing. High-performance engine builders in particular develop

close bonds with their balancing sources.

Even previously balanced components can benefit from a finer

state of balance. Not all balancing jobs are alike; parts

manufacturers may balance to tens of grams whereas balancers who

cater to performance engine builders are used to going to fractions

of grams (though such a fine balance may prove wasteful for

something like a drum). It may sound insignificant, but speed can

amplify the most modest imbalance.

You may be surprised to find just how common imbalanced brake

components are.
