Rear Brake Disc for AUDI A4

This Rear Brake Disc for AUDI A4 NO. 8E0615601Dis specially designed for the rear axle of Audi A4 B6/B7 (chassis code 8E). Essentially, it is a solid disc made of high-carbon grey cast iron, with a handbrake drum integrally cast at the disc center. It strictly follows the original factory design for direct installation without any modifications.

What is the actual driving experience after fitting this disc on your vehicle?

Instead of just looking at technical parameters, let's talk about real road performance. Most drivers of Audi A4 B6/B7 fall into three typical usage scenarios as follows.

Scenario 1: Daily urban commuting with fixed daily routes
Common annoyances include rust buildup inside wheel hubs while waiting for traffic lights, and strange squeaking noises from the rear wheels when moving slowly in parking garages. All non-friction surfaces of this disc are coated with electrophoretic paint, maintaining a neat iron-gray appearance visible through wheel spokes and preventing edge rust shortly after car washing. The surface finish roughness is controlled within Ra 1.0-2.0μm. Paired with qualified ceramic brake pads, it delivers steady and linear braking response with barely any high-pitched squeal, ensuring a quiet ride for elderly passengers and children.

Scenario 2: Audi A4 Avant station wagon for family weekend trips with luggage
The rear axle bears heavy loads. Thermal stress on rear brake discs rises sharply during long downhill drives or sudden speed reductions on highways. Though constructed as a solid disc, its standard 10-millimeter thickness and HT250 cast iron base provide reliable heat storage capacity. Combined with engine braking, it stays within safe operating temperature ranges. Every single disc undergoes individual dynamic balance calibration before delivery, eliminating subtle jitter transmitted from the rear axle to seats during high-speed cruising for a comfortable rest experience for rear passengers, offering more practical improvement than suspension upgrades.

Scenario 3: Manual transmission or S-Line sport version for occasional mountain road cornering
Repeated moderate heavy braking before continuous bends subjects rear discs to constant heating and cooling cycles, which may cause minor disc warping and rear-end shaking due to thermal stress. Adopting GG25 high-carbon alloy cast iron with evenly distributed carbides, the disc boasts outstanding resistance to thermal fatigue. It maintains stable performance during aggressive driving and avoids transmitting vibration to seat backs, provided you refrain from washing the overheated disc with cold water immediately after intense driving.

Many shops dare not show their workshops, while we want you to see how meticulously we work.
Processing Details: After raw blanks are fed in, all parts are machined in CNC machining centers. A single clamping operation completes the precision turning of outer circles, disc surfaces, center holes, bolt holes and inner diameters of handbrake drums. This processing method ensures the concentricity between disc surfaces and center holes is controlled within 0.03 millimeters, fundamentally reducing lateral runout. After machining, inspectors conduct random checks on thickness and parallelism using digital micrometers. Dial indicators are applied to test the disc runout of every single piece, and unqualified products are directly scrapped. Every finished piece undergoes weight removal correction on an automatic dynamic balancing machine, with no random sampling - each item is processed individually.

Surface Treatment Technology and Advantages: Instead of ordinary silver paint with simple spraying treatment, we adopt cathodic electrophoretic coating. Discs are hung on assembly lines and go through degreasing, phosphating and pure water cleaning procedures. Then they are immersed in electrophoretic paint tanks. Electric fields drive paint particles to adhere evenly to every crevice of metal, fully covering ventilation ribs and inner drum walls. The coated parts are baked in a curing oven at 170 to 185 degrees Celsius for 30 minutes, forming a 25 to 35-micron-thick coating with outstanding adhesion. The coating passes a 720-hour neutral salt spray test, resisting rust and blistering on edges. After installation, non-friction areas inside wheel hubs stay clean all year round, avoiding the shabby rust peeling phenomenon common to low-grade products after 20,000 kilometers of driving.

I drive an A4 B7 1.8T. Does the original rear brake disc come with an integrated parking brake drum? Can I install this disc directly?
Rest assured, it is a direct fit. The part number 8E0615601D corresponds to a solid brake disc built with a 170mm internal parking brake drum. It perfectly matches your original brake calipers, parking brake mechanism and hub dimensions, with no adapter rings required.

I have to pull the parking brake all the way up just to hold the car in place. Will replacing only the brake disc fix the issue?
Weak parking braking usually results from severely worn brake shoes inside the drum or a seized automatic adjustment mechanism. You need to fit a new set of parking brake shoes along with the new disc, and adjust the drum clearance strictly following the mentioned method. After proper adjustment, the parking brake will firmly engage with just two or three clics.

Can I just replace the disc and keep the old shoes? They still have plenty of thickness left.
It is not recommended. The surface of old brake shoes forms a hardened friction layer shaped to the uneven surface of the worn old disc. When paired with a new disc, only a small portion of the surface makes contact. This reduces braking efficiency and tends to cause vibration and abnormal noise. Saving minor costs now will lead to more troublesome problems later.quality
