Speedway Motors Brake Replacement Kit

Beating The Drums

Engines get all the glory, but in terms of driving enjoyment, brakes can make, or break, a car. Having tons of horsepower is useless if the car's braking system is sketchy. This is especially true of older Chevys that still run four-wheel drum brakes; or worse, a system without the aid of a power booster.

It's not that this system is inherently "bad," after all; cars ran this type of brake system just fine for decades. But, given the stopping prowess of modern cars, we've grown accustomed to better. In addition, it doesn't help that all of the cars around you can stop in under than 130 feet while your Chevy needs quite a bit more space. For these reasons one of the best upgrades you can perform on your classic Chevrolet is a drum to disc conversion.

We all know there are big-brake systems on the market. But those kits cost equally big bucks, and they simply don't work for the guy looking to run 15- or 16-inch wheels. Besides, many gearheads don't plan on attacking the track. They just want something that will better keep them from eating the bumper of the car in front of them on the road.

Speedway Motors has a collection of kits that lets those looking to ditch under performing drum brakes, in favor of their more modern disc cousins, and in a wallet friendly bolt-on way. To see what's involved, we ordered up some parts and headed over to Don Lee Auto to knock more than a few feet off of a 1965 Chevelle's stopping distance.

Drum 2/19

1. Drum brakes get the job done, just not nearly as good as their disc brake counterparts. They are even worse when coupled with the higher horsepower engines found under today’s hoods.

Remove Drum Shoes And 3/19

2. To make room for the new stuff, we first had to ditch the old. The drum was pulled and the old shoes and springs were removed. That left us with the backing plate, which was held to the spindle by three bolts at 12-, 4-, and 7-o’clock positions.

Stock 4/19

3. Our reward was one grungy spindle. Now, this spindle could be reused, if the upper pad was milled down by 0.610-inch. Of course, the other problem is that the upper bolt hole is smaller than the new bolt for the disc brake kit. This can be worked around, but there’s a much easier option.

Speedway Motors Disc Brake 5/19

4. The easier option is this disc brake Speedway spindle (PN 910-34900, $125 per pair). It’s forged steel and retains the stock height. Given the price it was the smarter way to go, unless you own a mill, which we don’t.

Speedway Motors Chevelle Front 6/19

5. This was the perfect time to rebuild our Chevelle’s front suspension so we picked up this complete kit from Speedway (PN 917-3220, $200). It included inner and outer tie rods, tie rod sleeves, center link, idler arm, and both upper and lower ball joints. Nothing fancy here, but having all these parts in one convenient kit sure beats hunting them down at the local parts store.

New Ball Joints 7/19

6. With the new ball joints installed we then attached our freshly painted disc-brake spindle.

Keep Tire Rod Length The 8/19

7. We also went ahead and installed the rest of our new steering components. To keep our alignment in the ballpark, we set the tie rod assembly at the same length as the one we removed from the ’65.
