Special Tools Used In Brake Service
Getting The Wheels Of The Vehicle Off The Ground
Removal Of Calipers From Mounting Brackets
A good set of wrench sockets and open-ended wrenches is essential for breaking the bolts loose that secure your caliper to its mounting bracket. Once the caliper is unbolted, using a wire hanger or plastic zip ties to hang the caliper and support its weight properly will prevent stress and damage to the flexible brake hoses. Some calipers may require a hex-head (also known as "Allen head") socket or Torx head socket to remove the bolts.
After pulling the old brake pads out of the caliper, a caliper piston reset tool will make it easy to compress pistons back into their housings to provide clearance for new brake pads. Depending on vehicle application, some caliper pistons may need to be rotated (or "rewound") back into the caliper housing – a specially designed universal adapter piece will make that process easy. Should you own more than one vehicle, you can consider a kit which offers adapters in multiple sizes.
Disc Brake Pads And Rotors
Once caliper pistons have been compressed, you're ready to put your new brake pads into place. Before doing so, clean the pins that the caliper slides on, then apply fresh brake parts lubricant. To quell brake pad vibrations and resultant noise, coat the back side of the brake pads with the caliper lubricant as well. Be sure to NOT get any of this lubricant on the friction surfaces of the pads or rotors!
If you'll be replacing brake rotors, removal of a small bolt or bolts that secure the rotor to the wheel hub is sometimes required. As with removal of calipers, an Allen Head (or hex) socket or Torx head socket may be necessary on some vehicles.
Brake Fluid Bleeding
If you've opened up the brake's hydraulic system to replace a disc brake caliper or master cylinder, or simply want to follow your manufacturer's brake fluid maintenance recommendation, you'll need to flush out the old fluid and replace it with new fluid by bleeding the entire system. If you'll be bleeding brakes with the help of someone else to step on the pedal, a simple brake bleeding kit with some rubber elbow fittings, a bleeder tube, and a bottle for the old fluid being discharged will make the process mess-free.
If you'll be bleeding the brakes by yourself, you have a number of options, including a clever one-way hose which allows brake fluid out but stops air from re-entering. Either way, a specially shaped brake bleeder wrench makes it easy to open and close bleeder valves on each caliper. Some examples we offer are the OEM Tools One Person Brake Bleeder Kit, CTA One Man Brake Bleeder Kit, and the Powerbuilt One-Man Brake Bleeder Master Kit just to name a few. If you really want to work like a pro, consider investing in the Symtech Brake Flush Assistant – a power-operated machine that creates a constant level of desired pressure in the brake system, allowing a single user to flush and bleed an entire brake system in less than 15 minutes.
Drum Brakes
When you find it's time to replace your drum brake shoes, brake drums, or parking brake components, CARiD has the parts AND tools you'll need to perform the job yourself. Once the drum is removed, a T-handle brake shoe spring removal tool for American vehicles with big springs will make easy work of getting the shoes off. One hook grabs the spring as another arm of the tool wedges it off. Some import cars with smaller hold-down clips on the brake shoes may benefit from a compact, circular-ended brake clip tool.
When you're ready to adjust the clearance between the brake shoes and drum, a starwheel adjuster spoon will allow you to rotate the starwheel adjuster on the drum brake assembly through a hole in the backing plate. We also offer universal drum brake repair kits that include the spoon along with a selection of retaining spring tools and return spring tools. If you are rebuilding your drum brake wheel cylinders (a must if new replacements are not available), a brake hone tool makes the process easy when attached to a drill.
