Weak Jacobs exhaust brake
I have an 03 with a Jocobs brake that was on the truck when I bought it last year with 140,000 miles and although it worked, it was pretty weak. Now at 210,000 miles the braking power is almost null. You can barely hear it turn on.
What could be causing this or is the pump just worn out?
