| B340714 | 2019-01-07. Service bulletin. SERVICE BRAKES, HYDRAULIC. "Carbon Ceramic Brake Noise. INFORMATION ""M"" vehicles are designed for high-performance, spirited driving. To accommodate this type of driving profile, a braking system which exceeds the standards for handling heavy brake forces, extreme temperatures, and excellent stopping power at high speeds is required. ""M"" vehicles can be ordered with the optional ultra high-performance braking system, featuring perforated carbon ceramic brake discs designed for circumstances similar to those encountered on racetracks. The carbon ceramic brakes were designed to improve braking efficiency, and dramatically increase braking performance along with a significant reduction in weight. When developing the carbon ceramic brake system, the main focus was on braking performance for the sporty-minded driver, while accepting the comfort limitations of functional noises at slower speeds and when coming to a stop. Please inform the customer that the carbon ceramic brake system's functional noises (squealing/honking), are a known characteristic for this type of material, and are only a small trade-off for the improved braking performance. These functional noises have no effect on the performance, operational reliability and durability of the brakes. Part replacement will not provide a remedy for the noise; this is a known characteristic of the high-performance brake system. More information on the performance and operation of these brakes can be found in the Owner's Manual under ""M carbon ceramic brake."" WARRANTY INFORMATION Not applicable." |
| B340117 | 2018-11-26. Service bulletin. SERVICE BRAKES. VIBRATION WHILE BRAKING. Vibration while braking is noticed: ? Most commonly when coming to a stop from higher speeds ? Less prominent when brakes are cold. ? After wheel balancing, the problem still exists. ? All other diagnosis according to SI B34 10 16 have no results. Over time, the original style NAO brake pads can develop friction variations. |
| 340614 | 2018-11-13. Service bulletin. SERVICE BRAKES, AIR:DISC:CALIPER; SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:DISC:CALIPER; SERVICE BRAKES, HYDRAULIC. M5 and M6 Front Axle Brake Squeak with Compound Brake System. A squeaking noise can be heard when braking from a slow speed. This situation may apply to M5 and M6 vehicles fitted with the metallic brake pads (P/N 34 11 2 284 869). These pads can be identified by the absorber weights at the top and bottom. Due to the design of the fixed caliper brake system, an unfavorable interaction between components may cause a squeaking noise. |
| 340414 | 2018-11-13. Service bulletin. SERVICE BRAKES, HYDRAULIC. Diagnosis of Compound Brake System Complaints in M Vehicles. INFORMATION 1. Visible cracks are caused by high thermal stresses during rapid heating and cooling of the brake discs. Braking from high speed with cold brake components (less than 212 degrees F) increases the likelihood of cracks to form. These surface hairline cracks are usually spread over the entire brake disc friction area, and have no negative influence on the durability or braking performance. The rotors should not be replaced only for their appearance reasons. When performing routine service on the brake system (pad replacement due to wear), the brake discs should be replaced if surface cracks are found to be greater than 13 mm, or if the brake disc thickness is below the minimum thickness. Always replace brake discs in pairs (per axle). Install new brake pads when replacing discs. By doing this, the service life of the friction pad surface is increased, and an even material loss is ensured. 2. Vibrations and/or steering wheel torsional vibrations during braking are caused by applying the brakes on discs with minimal to heavy corrosion. These vibrations are most noticeable when braking from high speeds with cold brake components (less than 212 degrees F), and will diminish with normal everyday operation. Parts replacement is not required. 3. After high brake loads, running noises can be heard when applying the brakes, and may also be heard to a limited extent after the brakes are released. (See the note in the Owner's Manual). These noises are reduced during normal everyday operation, due to further erosion of the brake pad friction lining. Visible surface cracks or craterlike recesses on the brake pad surface are caused by a minor difference in the material of the pad lining, which will decrease with further operation and should not be replaced due to their appearance. |

| B340516 | 2018-11-05. Service bulletin. SERVICE BRAKES. CBS BRAKE PAD CALCULATION AND CORRECTION. When a vehicle comes into the workshop for any repair or maintenance job, the bundling calculator recommends a brake maintenance checkup. No brake warning light is illuminated. CBS shows 3,107 miles or slightly higher for the next brake service displayed via Key Reader, or vehicle's Control Display (in Vehicle Info/Status/Service required/Brake pads) CAUSE CBS calculates the remaining brake pad wear based on brake pressure, speed, vehicle specific parameters (i.e. NAO pads), brake temperature as well as cumulative brake application time. Due to variation of these parameters and outside environmental influences, this calculation can deviate from the real brake pad wear. Starting from the above-mentioned production dates of the vehicles indicated, the CBS brake pad wear calculation has been changed, and is now based only on the brake pad wear sensor. Important Note: To avoid a too-slow wear prediction, the CBS brake model will estimate the need for repairs, in some cases, rather early. Calculation will level at 3,107 miles and stay at this value until the CBS brake pad wear sensor is triggered. https://www.bmwtis.net/tiscode/cgi-bin/bulletin.aspx?sie_path=/tsb/bulletins/htm_store/36...11/8/2016 Page 2 of 2 After the sensor is triggered, the CBS mileage will count down indicating to the customer that the brake repairs will be due. |
