The poorly-functioning ABS system is the problem, and this new dual-diaphragm brake booster from Dave's Customs Unlimited is the solution. Dave's Customs owner, Dave Seger, custom-configures each booster system with a master cylinder that's right for each Jeep's axles, brakes, and tire size. Dave informed that the factory ABS system didn't work well even when new and there's no doubt the system on this Jeep needs some new parts thrown at it to work as designed. Instead of throwing parts at a fundamentally flawed system, we're going to throw that system away for something that gives real braking power. Stay tuned for Part III.
