331-73679 DFC OE Replacement Brake Caliper (Rear Left for Audi A7 2012-2013 Quattro Models)

The DFC 331-73679 rear left caliper is engineered to restore precise hydraulic performance in Audi A7 and A6 Quattro series vehicles from 2012 to 2013. Designed with a silver zinc coating, this premium caliper provides superior corrosion resistance and durability in demanding fleet environments. When brake response becomes sluggish or a spongy pedal develops, internal rubber seals and pistons often suffer wear, leading to pressure loss and uneven brake pad engagement. This caliper assembly addresses those issues by offering a direct OE replacement that ensures consistent clamping force and reliable brake operation under severe-duty conditions.

Constructed to meet or exceed OEM specifications, the DFC caliper features a robust casting and precise piston fitment, delivering immediate hydraulic response and minimizing volumetric expansion during heavy braking. Its heavy-duty design makes it suitable for commercial fleet applications requiring high-pressure endurance. Proper installation of this caliper involves verifying the fitment against existing hardware, ensuring correct piston retraction, and confirming that mounting brackets are free of corrosion or damage to maintain optimal caliper function and brake pad alignment. Regular inspection of brake lines and caliper mounting points is critical to prevent fluid leaks and chafing, which can compromise braking safety.

This caliper fits a range of 2012-2013 Audi A7 Quattro, A6 Quattro, and Q5 models, providing a reliable, long-lasting solution for fleet and service vehicles. Its corrosion-resistant zinc finish extends service life in harsh environmental conditions, ensuring your fleet maintains consistent braking performance. Whether tasked with routine maintenance or addressing brake system failure symptoms, this caliper assembly guarantees a high-quality, cost-effective repair that restores full braking capacity and safety integrity in heavy-duty applications.
