Question:

Brake Pro 9300. Cycles about every 3 1/2 minutes, manual says this is not normal, how-ever I have checked air lines and fittings and cannot detect an air leak. I also read that I need a 20 amp power supply, how do I check this, it is on a Jeep Wrangler 2004 model. If you could help I would be very appreciative. Thanks,

I spoke with my contact at Roadmaster about the problem that you are having with your Brake Pro 9300. He said that if you have checked the air lines and fittings and cannot find a leak then it is most likely the air compressor or the magnet. Since the Brake Pro 9300 was discontinued back in 2002 there are no replacement parts available so you will probably want to look at getting another system.

If you really liked the Brake Pro 9300 then Roadmaster has another solution that worked just like it. The Roadmaster Even Brake # RM-9400 uses the same technique that involves applying force to the brake pedal on your 2004 Jeep Wrangler to activate the brakes.

This system pulls power from a 12V power source and requires 15 amps of power. You can test the amperage of your power source by using a Multimeter # PT89ZR.
