Re: my cj5 has drum brakes all 4
I thought disks were standard in 77? Either way you should have a proportioning valve mounted on the inside of the driver's frame rail to the left of the tranny bellhousing. Do not bother trying to do anything special to the prop. valve. Just make sure you use the correct tool to press/pull the little button while you bleed the brakes. If you encounter any problems cut the damn thing off and add an adjustable prop valve for $40 from Summit or somewhere.
