weak brakes at speed
My 3400RL has good brakes at 30-40 but very poor brakes at 65 mph, dealer removed original 16 gauge wire and installed 10 gauge wire from hitch pin to axles (as required by dexter axle book) now have 12 amps but poor brakes at 65 mph. If I use the manual control lever at 65-70 mph with control set for max (12 AMPS) without using TV brakes, very little happens, you can hardly tell brakes are on.
Brakes are adjusted tighter than normal and this continues with new early 07 unit 6000 lbs axles, white mag wire. I feel the problem is the LARGE HOLES, behind the studs in the brake drums. The magnets are right over two of the 3/4 inch holes at one time so there is less metal for magnetic pull. Total panic stopping distance from 70 is over 500 feet in dry perfect conditions. On same payment, truck alone stopped easy in 210 feet. 500 feet is bad enough on dry payment but who knows how far on wet payment.
My question is this, has anyone with a 3400 RL with the large studs tried this test with manual control lever at 65 mph to see if you have good enough brakes to slide a tire or even close to sliding.
thanks for any info
