Some of the most critical components of your BMW are those of the brake system. Whether you are performing maintenance on your daily driver or stocking up on performance brakes for race season, keeping your brakes in working order is paramount to enjoying your car. At Turner Motorsport, we have everything you need to replace or upgrade your brake pads, brake rotors, brake lines, and brake fluid. Choose from our excellent selection of brake components to keep your BMW stopping confidently.
On modern cars the ABS system is also tied in with other features and systems. ABS sensors are used for speedometer readings, traction control, stability control, and other components. So when a sensor fails it's not just affecting your braking but cascading through the rest of the car as well. Typically there will be an ABS light on in the dash cluster but the SES/CEL light may also come on which will require a trip to the dealer to have the fault analyzed.
There are other components of the ABS system that are common failure or known weak points - control modules, pressure sensors, and relays. We keep in stock many of the parts that are prone to common failures, allowing you to get safely back on the road in short order.
Here at Turner Motorsport, we're all about how quickly you can go from 0-60. But if you're really serious about track days like we are, you should be equally as serious about your 60-0 time. Braking is vital to improving lap times. If you're serious about progressing as a driver, then a big brake kit is essential for you.
When servicing your brake system, we recommend adding brake compounds onto your order to keep braking components - specifically your caliper guide pins, bracket contact points and brake pad backing plates - lubricated, preventing brake squeal/noise.
Servicing your brake system with the best possible fluids for your setup is just what your BMW needs to have the perfect pedal feel and performance. Perform brake services that involve bleeding brake fluid with our recommended bleeder tools to get the job done quickly and effectively for the shortest downtime. All the fluids and specific tools you need are listed on this page and ready to help keep your BMW brake system in perfect working order
We offer OEM replacement brake lines as well as upgraded stainless steel brake lines.
We offer OEM replacement brake lines as well as upgraded stainless steel brake lines.
Stainless brake lines are a must for any track driven BMW and make a great upgrade on street cars as well. Brake lines should be replaced every few years anyway and braided stainless lines offer an additional layer of protection. Rubber brake lines deteriorate from the outside and inside. The external rubber can become stiff, crack, or get damaged by debris. The stainless braiding and Teflon inner coating help protect the outside of the line from debris. And with a stronger material the line will not expand or swell under extreme braking conditions. Stainless brake lines provide a firmer positive pedal feel under hard braking by greatly reducing the expansion that can be found in stock rubber lines. The internal of old stock rubber lines can become constricted over time even if the exterior looks normal. With a blockage or restriction you can have serious braking issues that often go mis-diagnosed as warped rotors, stuck calipers or bad ball joints. Make sure you don't overlook your brake lines! All brake lines, rubber or stainless, should be replaced every few years and any time you replace a brake caliper.
These are the highest quality stainless brake lines that meet DOT specs at great prices. Our lines are made with stainless braiding and Teflon inner lines. The fittings are the correct BMW type and sizing and with swaged fittings and an additional rubber boot for protection.
Turner Motorsport offers brake pads for every environment and need. Whether you're daily commuting, backroad carving, autocrossing, hot lapping, sprint racing, or endurance racing we have a brake pad brand and pad compound that will work within your requirements. We are one of the largest retail sources of BMW brakes in the world and we avoid overlapping brands and compounds. This means we can offer specific compounds and types that match with your driving environments and your braking characteristics. With our long history of building street and track BMWs we have a depth of insight and knowledge on braking performance unparalleled in the industry. And our racing brakes have been developed with feedback from some of the best sports and GT drivers ever.

Similarly to brake pads, the brake rotors can be matched to specific driving conditions and intended use. For solely street use the design and characteristics particular to each rotor are not big factors in overall braking performance. For instance, a cross-drilled rotor will not significantly improve braking under street conditions. Improved stopping performance will come mostly from your brake pads. Some rotor designs perform better under racing conditions with racing pads but, generally, all rotor types can be used on the street. For race track use we typically recommend a slotted or blank stock rotor. Any 2-piece floating rotor is superior to anything else and those are our first recommendation when available. For more information on the brake rotors we sell, check out our rotor buying guide.
All of these rotors are manufactured to meet BMW's specs for each vehicle application. Our standard rotors are sourced from original manufacturers for BMW (OEM), performance alternatives, or straight from BMW themselves. In some cases BMW Motorsport and BMW Performance will have their own rotor upgrades. Our Cross-Drilled, Slotted, and Drilled+Slotted rotors are manufacturered by StopTech - a global leader in braking technology and the braking technical partner to the Turner Motorsport racing team.

Does your BMW need pads and rotors? We've done the research for you and put together packages with pad and rotor brands we trust, specifically catered to your vehicle. Additionally, we have performance rotor and pad replacement packages that feature slotted rotors and an aggressive brake pad, for those who want performance braking with your stock caliper setup.
Brake calipers require periodic maintenance just like the rest of your braking system. The number one problem with brake calipers is caused by rust. The caliper and the internal piston are made from cast iron and is prone to rust just like any other ferrous material. Not replacing your brake fluid regularly will lead to water entering or forming in the system and that will rust the calipers and hard brake lines from the inside out. A rusted caliper will cause the piston to seize, creating a stuck caliper, dragging brakes, wheel vibrations, pulling to one side, excessive brake dust and heat, or even a total loss of brake function on that wheel.
We offer brake caliper rebuild kits but sometimes the condition of the inner piston is just not safe to re-use. Unfortunately you really don't know for sure until you have removed the caliper and taken it apart. As a convenience we offer freshly rebuilt calipers. Each caliper is cleaned and sand-blasted to remove surface rust and dirt/grime. The pistons are rebuilt with new seals and dust boots and re-installed into the caliper housing. The caliper you get is ready for a direct replacement on your car! There's no mess from brake fluid leaking everywhere and no fighting to get the piston seals to fit. Replacing the calipers with newly rebuilt units does not take any more signifcant time during a typical brake pad/rotor overhaul. Rebuilt calipers are sold on a core exchange basis so we need your original calipers returned to us.
Plan on tracking your car? Going to be using real track/race pads? You're going to need brake cooling ducts and hose. Brakes create lots of heat and temps can rise to damaging levels. Excessive heat will burn up caliper seals and dust boots, boil brake fluid, lead to rapid pad wear, inconsistent pedal feel, damage rubber boots on suspension ball joints, and other problems. Racing brake pads are designed to work in very specific temperature ranges so to prevent them from exceeding those temps race teams rely on brake cooling ducts, silicone hose, and bumper ducts.
We have designed and produced advanced brake backing plates that fit behind the wheel bearing hub. The backing plates have an inlet duct that directs air to the center of the hub/rotor. From there, cooling vanes in the rotor draw the air through the rotor to cool it. By keeping the rotor cool it won't transfer as much heat through the pads, caliper, and rest of the braking system. Our kits are designed to fit to the hub without having to remove the hub/bearing.
The brake master cylinder is responsible for distributing fluid from the reservoir to the front and rear brake systems. The fluid reservoir actually sits on top of the master cylinder with hard metal brake lines running out of it. There are a few places where the master cylinder can leak and cause a spongy or soft brake pedal. The inside has several pistons with o-rings and seals that can fail and allow brake fluid to escape. Likewise, the external metal lines also have o-rings where fluid can seep out or let air/moisture in.
Parking Brakes - also know and emergency brakes, or hand brakes, help to keep your BMW stationary when parking or on an incline. Over time the parking brake shoes tend to wear out making it more difficult to secure the car. We recommend inspecting the parking brake shoes, cables and associated hardware any time rear rotors are replaced.
