Long reply but a lot of info.
I'm on my second Ready Brake equipped car. Both installs I did myself along with the base plates. The second install on a 2005 Honda CRV I had problems with the brake pedal not retracting fully even when the CRV wasn't being towed. Turned out to be am under dash cover that the brake pedal cable clamp was hanging up on or in other words an installer error.
There are a couple of test you can try to pin down where the problem is, the 4Runner, the cable in the 4Runner, the tow bar surge mechanics or the attaching cable.
Also, if you have a Ready Stop Brake-Away kit it must be fully independent from the surge brake system provided with the tow bar.Here is what my set up looks like. I do not have the brake away option installed at the time the image was taken.
Needed a bit more slack in the cable. First toad 1998 Arrord.
1. Check under the dash for a repeat of my error but I would have expected the brakes would be hanging all the time as mine did. The end of the cable should be bolted firmly to the fire wall. The angle of the cable from the firewall hole to the cable clamp should be as small as possible so the cable doesn't saw thru the attaching hardware.
2. At the front of the 4Runner give a tug on the brake cable. Can you pull it out maybe an inch or two? Was the movement smooth and once released did it retract all the way? Have a second person push on the brakes while you watch the cable end. Again smooth movement and full retraction? Take note of how far the cable extends out from the 4Runner.
If #1 and 2 appear OK problem isn't the 4Runner but if not then you'll need to look deeper into the 4Runner installation.
Install the tow bar to the coach and 4Runner but don't attach the cable to the 4Runner. Both tow bar arms need to be in the lock position and the 4Runner needs to be centered behind the coach just as if you were going down the road. Drive around the block if necessary.
3. Using a second person, while you watch the surge lever arm on the tow bar, place the 4Runner into drive while holding the brakes on. Slowly start letting off on the brake. As engine idle starts moving the 4Runner forward did the surge lever arm extend? A light touch of the gas pedal might be necessary to over come the bar spring and to get full movement of the surge lever arm. Place the 4Runner in neutral (may need to use reverse) and allow the tow bar to relax. Did the surge lever arm fully retract? If the lever arm is extending and fully retracting the surge mechanics in the bar are good. If not you'll need to send the bar back for repair.
Now connect the cable between the bar and the 4Runner. There should be some slack in the cable (maybe an inch or so of drop) and you should not need to pull on the 4Runner cable to connect the tow bar cable.
4. With the second person still in the 4Runner put it in drive and rerun the first part of step 3. In addition to the surge lever arm movement the 4Runner operator should feel the brake pedal drop away from their foot as the surge activates further and further. You can even give the 4Runner a touch of the gas pedal as they did in test #3 which will force the surge system to its maximum movement limit simulating a panic stop of the coach. Is there any remaining brake pedal left? If not than the 4Runner brakes are lock by the tow bar as they should. The attaching cable should be tight. If the suge arm is fully extended but there is still brake pedal movement in the 4Runner you might have more slack in the cable than lever arm movement can account for.
5. With the brakes still locked on the 4Runner place the 4Runner in netrual and shift the second person from the 4Runner to the coach. Start the coach engine and with the coach brakes on place it in drive. Slow lift off the brakes of the coach and allow the engine idle to inch it forward. As the coach moves the pressure will come off the surge mechanics and the lever arm will retract. Did the lever arm retract completely? Did the cable return to the same slack amount as before? Did the 4Runner cable return to its normal position as noted in test #1?
If the lever arm doesn't not fully retract the problem is in you tow bar. If the arm retracted but the cable did not slacken the cable is hung up on an obstruction. If the cable slackened but the 4Runner cable did not fully retract the problem is in the 4Runner but I would have expect test #1 or 2 would have exposed such. Run test 5 a couple of times since it a dynamic test of the complete system and allows you to observe what occurs while going down the road.
Not sure about the cable attachment you posted about. Any chance of posting an image?
