Video: Brake Pedal Maintenance With AFCO’s Ben Baker

 

We’ve learned to trust AFCO’s Ben Baker when it comes to setup and maintenance issues on stock cars, modifieds, and dirt late models. Baker has over 10 years experience as a dirt late model crew chief with more than 50 wins to his credit. With over 20 years in the racing business, Baker has logged over 10 of those years in dirt track suspension with the AFCO Performance Group. He has also helped the OneDirt readers by providing critical chassis setup information in articles like the recent Second Gen Camaro Street-Stock Suspension Setup For Dirt article.

When it comes to proper setup, Baker explains that the pushrods need to be screwed into the clevis the same amount. Not that it has a huge impact on the hydraulic pressure on the front or rear, this is simply an effort to keep as much travel in the bias adjuster from front to back, which allows for more adjustment and not getting bound up and preventing a full range of brake bias adjustment. According to Baker, there are about 26 rounds of adjustment from front to rear. If you have significantly fewer turns than that, make sure the pushrods are adjusted evenly and check for any damage or burrs on the clevis. Make sure the pivot points and adjusting bar are properly lubricated.

If you mount their rear brake master cylinder to the left, the adjustor is turned to the right to get more rear brake bias. Obviously if you mount the rear brake master on the right, you turn the adjustor to the left for more rear brake. 

Baker recommends cleaning, lubricating, and cycling the brake bias bar weekly just to keep it operating correctly. Making sure the bias crank works smoothly and the pushrods are not bent is another key to successful maintenance of the system. Baker assures us that the system is pretty trouble free if you do the routine maintenance on the bias adjuster.

Stay tuned for more helpful tips and tricks from AFCO Racing.
