Rear Brake Disc for BUICK Envision

Factory-tested OEM specification for Buick Envision rear brake Disc Part No.13583685]: Outer diameter 288mm, standard rotor thickness 12mm, legal discard thickness limit at 10mm; equipped with 5 mounting bolt holes, center bore diameter 70.7mm, net single-piece weight 5.2kg. Built as a full solid design without cooling vanes, this rotor is precision OEM-fitted for Buick Excelle GT/XT and Monza models, as well as rear brake assemblies of overseas-spec Chevrolet Cruze sharing the same GM platform. It serves as an OE replacement component with consistent small-batch repeat orders from medium and small auto parts wholesalers across North America and Australia.

OE part number 13583685 is an OEM factory-fit component for General Motors (GM), precisely compatible with the rear brake assemblies of the 2015-2023 Buick Verano Hatchback/Sedan, 2016-2022 Buick Excelle GT/XT and the first-generation 2013-2019 Encore. These three compact family cars are mainly used for short-distance urban daily commuting with frequent stop-and-go driving during morning and evening rush hours. Many long-term vehicle owners complain that the stock factory brake rotors tend to develop minor surface warpage after two to three years of service, accompanied by high-pitched squealing during low-speed braking on rainy days and rust-seized wheel hub bolt holes that become extremely difficult to disassemble.

Buick 13583685 rear brake disc undertakes a vital role in automotive disc brake assembly. Made of high-quality cast iron and optimized composite materials, it fits the wheel hub perfectly and rotates coordinately with wheels during travel.
When drivers apply the brake, caliper brake pads will closely clamp the disc surface. The friction generated converts vehicle running power into heat rapidly, achieving smooth speed reduction and stable braking performance. being a reliable pick for global auto parts suppliers and aftermarket replacement.

This Rear Brake Disc of BUICK Envision 13583685 adopts sophisticated multi-layer surface processing technologies.We apply precision surface grinding, structural drilling technology, professional spray finishing and premium Dacro coating craft in production. These elaborate techniques refine disc flatness, greatly boost heat dissipation efficiency and strengthen high-temperature resistance, meanwhile realizing reasonable lightweight optimization.

The integrated craft brings excellent anti-rust and anti-corrosion capacity, extending service life greatly. It balances fine texture and practical performance, delivering linear and stable braking output in all scenarios, offering solid safety protection for daily driving.

Many Buick owners who drive frequently in northern regions on roads treated with snow-melting agents in winter or reside in humid coastal areas in southern China find that their original-equipment brake discs with part number 13583685 develop heavy rust around the center bore and mounting holes after just over a year of use. The rust seizes up wheel hub bolts, forcing repair shops to use cutting machines to remove wheels. To fix this common defect, we have upgraded to a graphene-reinforced zinc-aluminum ceramic composite spraying process, with full production procedures complying with the anti-corrosion testing standards specified in GM4652.

Step into our brake disc intelligent manufacturing workshop: witness how a chunk of iron transforms into a safety guardian
Have you ever wondered how the quietly working brake disc on vehicles evolves from a rough metal block into a high-precision safety component? Today, take a virtual tour of our modern brake disc mechanical processing workshop, and learn about the high-tech technologies and exquisite craftsmanship here in plain language.

First Impression of the Workshop: More Than Roaring Machines, But a Symphony of Intelligence
When you step into the workshop, you will not see workers covered in oil stains, but rows of neatly arranged numerical control equipment operating automatically.

Smart robotic arms flexibly grab brake disc blanks and accurately place them onto the production line. Most procedures including cutting, polishing and material transportation are finished automatically, just like watching an exquisite industrial ballet. Such fully automated production lines are the core secret behind our workshop's high efficiency and superior product quality.

We have introduced advanced equipment such as vertical CNC turning and milling composite machining centers. Acting as all-rounders in the workshop, these devices complete turning and milling processes in one go, featuring powerful processing capacity, fast working speed and stable machining precision.

Q: After installing brake rotor part number 13583685 on a 2020 Buick Verano, a squeaking noise occurs when lightly applying the brakes at low speeds. Does this count as a quality defect of the brake rotor itself?
A: In most cases, the noise is unrelated to rotor quality. The rear brake housing of the Verano has limited internal space; frequent stop-and-go driving in congested urban traffic can lead to glazing on the brake pad friction surfaces from excess heat, which is the primary cause of abnormal squeaking. First clean the contact faces of brake pads with isopropyl alcohol. Replacement of the 13583685 brake rotor is only required if single-side groove wear on the rotor surface exceeds 0.36 mm, lateral runout surpasses the factory specification of 0.039 mm, or rotor thickness drops below the minimum service limit of 8.2 mm.

Q: For the first-generation Buick Encore operated long-term in humid coastal cities with the 13583685 rotor fitted, how often should the vehicle be brought into a shop for brake system inspection?
A: For regular urban commuting, brake inspection is recommended every 20,000 kilometers alongside tire rotation. For coastal operating environments with heavy salt spray and prolonged rainy seasons, the maintenance interval is shortened to inspection every 13,500 kilometers. Three core inspection items include actual remaining rotor thickness, rotor face runout readings, and corrosion depth of bolt holes.

Q: At what remaining thickness (in millimeters) of the original-equipment 13583685 brake rotor on a Buick Excelle is it advised to pre-order a replacement rotor?
A: GM's official scrappage minimum thickness is set at 8.2 mm. For real-world vehicle usage, pre-purchasing new replacement rotors is recommended once residual rotor thickness reduces to 9.1 mm. This reserves material allowance for wear-in of new brake pads and prevents unexpected vehicle downtime caused by sudden complete rotor wear-out.

New Intelligent Production Line Launched
We are excited to announce the launch of our new fully automated brake disc production line in May 2026. This new line increases our annual production capacity by 500,000 units and improves product consistency significantly.

New EV Brake Disc Series Now Available
We have developed a new range of brake discs specifically designed for electric vehicles. These discs feature enhanced corrosion resistance and reduced noise levels, meeting the unique requirements of EV braking systems.

Here is an important reminder for DIY enthusiasts: when replacing rear brake discs on Buick Regal, LaCrosse and other models equipped with an electronic parking brake (EPB), never force the caliper piston back with a C-clamp. You must first activate the "brake pad replacement/service mode" via a diagnostic scanner to let the EPB motor retract the piston automatically. Alternatively, use a special tool that applies pressure while rotating clockwise to screw the piston back into place. Forcing the piston back manually will easily damage the lead screw assembly and EPB motor inside the caliper, resulting in costly repairs. Additionally, General Motors specifies a torque setting of 140 Nm for its rear wheel hub bolts, higher than that of most Japanese vehicles. Always tighten the bolts diagonally in two separate stages using a torque wrench; improper tightening causes warped brake discs that lead to persistent brake vibration no matter how much bedding-in is performed. Pay attention to these fine details, and the newly fitted brake discs and pads will deliver reliable long-term service.
