Automotive Brake Bleeder Screws

Automotive Brake Bleeder Screws

Automotive Brake Bleeder Screws are key precision components in automotive brake systems. They are installed on brake calipers to discharge air from brake pipelines, ensuring stable pressure and braking sensitivity of the brake system. Our Automotive Brake Bleeder Screws are made of high-quality medium carbon steel or stainless steel as raw materials, and are processed by precision turning and conical surface grinding.

Product Description

Automotive Brake Bleeder Screws are key precision components in automotive brake systems. They are installed on brake calipers to discharge air from brake pipelines, ensuring stable pressure and braking sensitivity of the brake system. Our Automotive Brake Bleeder Screws are made of high-quality medium carbon steel or stainless steel as raw materials, and are processed by precision turning and conical surface grinding. The sealing cone surface has high precision and fits tightly with the bleeder valve seat, which can effectively prevent brake fluid leakage. At the same time, the threads are smooth and the head structure adapts to standard tools, with convenient operation, which is an important guarantee for the reliable operation of automotive brake systems.

We can adapt to the brake caliper specifications of various vehicle models, provide Automotive Brake Bleeder Screws with different sizes and different cone angles, and support customization of bleeder screws with special structures such as dust caps and check valves to meet the design needs of different brake systems. The product surface can be subjected to various anti-corrosion treatments such as galvanizing, nickel plating and passivation to adapt to the complex use environment of automobile chassis and extend service life. Each bleeder screw undergoes strict cone surface sealing test, thread go-no-go inspection and dimensional inspection before leaving the factory to ensure that the sealing performance and assembly accuracy all meet the standards. For overseas auto parts customers, we can also customize production according to corresponding vehicle model standards and provide supporting accessories such as dust caps.

Quality Control

 

We implement strict quality control standards for all automotive brake bleeder screws, from material inspection when raw materials enter the factory, to cone surface precision control during processing, and then to 100% full inspection of finished products, checking layer by layer. The core inspection items include cone surface sealing performance, thread accuracy, dimensional tolerance and surface anti-corrosion layer adhesion, ensuring that each product meets the quality requirements of automotive parts. We accept product testing and inspection from third-party professional institutions. All products come with a 1-3 year warranty period. If there are quality problems such as sealing failure and unqualified threads, we will reissue and replace them for customers free of charge.

 

After-sales Service

 

We have established a complete auto parts customer service system. Before sales, we can provide free product samples and inspection reports, and customers only need to bear the international express freight; during the production stage, we can regularly feedback production progress to customers and provide real-time production pictures and video updates; after sales, the products come with a 1-3 year warranty period. If quality problems such as leakage and breakage occur under normal installation and use conditions, we will provide replacement services for customers at the first time. We promise to respond to all after-sales inquiries within 24 hours to efficiently and quickly solve various customer problems.

 

Payment Terms

 

We support flexible and transparent payment methods. For standard specification bleeder screw orders, 30% prepayment is adopted, and the balance is settled against the copy of the bill of lading; for custom orders, 40% prepayment is adopted, and 60% balance is settled against the copy of the bill of lading. We accept telegraphic transfer payment in mainstream currencies such as US dollars and euros. For large-volume long-term orders, corresponding tiered price discounts can be provided according to the purchase volume. All payment details are clear and transparent without any hidden fees, fully guaranteeing customers' capital safety and procurement rights and interests.
