Question:

Im told my brakes are obsolete. The are on my flatbed trailer manufactured in the 1980s. It is a four bolt pattern. Do you have anything that will work? What other information do you require? Please let me know. Thanks.

I would be more than happy to help you pick out a set of replacement brakes for your trailer. I am going to need to also know what the capacity of your trailer's axle's are, as well as the bolt pattern.

If you don't know what your bolt pattern is, check out the linked article that goes into detail how you can figure this out.

Form here we should easily be able to tell you exactly what you need. To give you an example, the part # K2R35S will fit 3.5K axles with a 4-bolt mounting flange, and a 5 on 4-1/2" bolt pattern.
