Improper adjustment of the brake shoes and mismatched wheel cylinders are the primary "gripe" of drum brake systems. A four wheel drum system can be safe and reliable, but all components need to be correctly selected, installed, and adjusted.

Misadjustment is the major reason people dislike drum systems. Maintenance and adjustment is easy, but it actually requires attention. Discs are self adjusting and easier.

All brake systems have front/rear proportioning valves. Having the correct valve and correct master cylinder are critical.
