Heavy-Duty Performance Auto Brake Parts & Conversion Components

 

Sourcing reliable braking hardware for classic vehicle restorations, drum-to-disc conversions, and custom hot rod builds requires exact dimensional tolerance and consistent material strength. JR Global manufactures a specialized portfolio of auto brake parts, focusing on structural and hydraulic components including disc brake conversion brackets, master cylinders, proportioning valves, pedal assemblies, and mounting hardware. Operating out of our manufacturing facility in Guangdong, we supply global B2B distributors, automotive aftermarket brands, and specialized restoration shops with precision-machined brake system hard parts built for demanding hydraulic pressures.

 

 
 
Product Range
 

Our production line covers critical hydraulic and mechanical brake system components engineered for vintage platforms and performance upgrades:

Brake Conversion Brackets

Precision-machined steel and billet aluminum brackets for mounting disc brake calipers on classic solid axles and spindles.

Master Cylinders & Boosters

Dual-reservoir master cylinders (cast iron and aluminum bodies, 1 inch and 1-1/8 inch bore options) and compact under-floor or firewall brake booster assemblies.

Proportioning Valves & Distribution Blocks

Adjustable residual pressure valves, proportioning valves, and brass distribution blocks for balanced front-to-rear brake bias.

Pedals & Linkage Brackets

Swing pedal assemblies, firewall mounting brackets, and mechanical linkage rods fabricated from heavy-gauge structural steel.

 

 
 
Key Features

High-Strength Alloy Matrix

Components fabricated from certified ductile iron, high-tensile structural steel plates, and 6061-T6 forged aluminum blocks to withstand high hydraulic and mechanical stress.

Precision CNC Machining

Critical mounting faces and hydraulic bores processed on multi-axis CNC milling centers to maintain tight dimensional tolerances within plus or minus 0.02 mm.

Controlled Hydraulic Integrity

Master cylinders and distribution components designed to handle high operating pressures without internal fluid bypass or structural fatigue.

Durable Surface Protection

Finished with corrosion-resistant zinc plating, industrial black oxide, or clear anodizing to resist road salts, brake fluid exposure, and environmental oxidation.

 

Application

Classic Muscle Car Restorations

Drum-to-disc brake conversion brackets and master cylinder upgrades for 1960s and 1970s American chassis platforms.

Hot Rods & Street Rods

Firewall-mounted pedal assemblies, under-floor brake pedal brackets, and compact master cylinder setups for tight chassis layouts.

Custom Restomods

Hydraulic proportioning adjustments and custom bracket fabrication for upgraded multi-piston performance calipers.

Manufacturing & QC

CNC Plasma Cutting & Milling: Raw steel plates and aluminum billets are profiled and milled via high-precision CNC machinery to ensure exact hole centers and edge alignment.


Pressure & Leak Testing: Hydraulic master cylinders and distribution blocks undergo 100 percent pneumatic and hydraulic pressure testing to verify seal integrity and prevent fluid leakage.


Metallurgical Verification: Incoming raw castings and metal bars are sampled for hardness testing (Brinell/Rockwell) and structural grain verification.


Dimensional CMM Inspection: Finished brackets and mechanical assemblies are verified using Coordinate Measuring Machines (CMM) to ensure zero-modification bolt-on installation.

FAQ

 

 

Q: What is the minimum order quantity (MOQ) for custom brake brackets?

A: MOQs vary depending on the product design and tooling requirements. For standard catalog items, trial orders starting at lower quantities are supported. For custom-engineered brackets requiring new CNC programming or stamping dies, MOQ is determined during the engineering review phase.

Q: What material grades are used for your disc brake conversion brackets?

A: Our conversion brackets are typically fabricated from high-tensile structural steel plate (such as Q355 or equivalent carbon steel) or forged 6061-T6 aluminum, selected to prevent flex under high caliper clamping loads.

Q: Are master cylinders pressure tested before shipment?

A: Yes. Every master cylinder undergoes 100 percent pressure and seal testing to verify internal check-valve function and eliminate any risk of fluid bypass or leakage under operational pressures.

Q: Can you manufacture brake components based on our proprietary CAD drawings?

A: Yes. Our engineering team accepts CAD drawings (STEP, IGES, PDF) to evaluate structural feasibility, thread specifications, and hydraulic port configurations for OEM/ODM projects.

Q: What bore sizes are available for your dual-reservoir master cylinders?

A: We offer standard bore configurations including 1 inch and 1-1/8 inch options suitable for various drum/disc and disc/disc brake system combinations.

Q: What surface finishes are applied to prevent corrosion?

A: Steel components are finished with heavy electroplated zinc or black oxide, while aluminum parts receive protective anodizing coatings to withstand brake fluid contact and environmental moisture.

Q: How do you ensure bolt-on accuracy for restoration applications?

A: We use dedicated CNC machining fixtures and CMM inspection protocols to verify mounting hole center-to-center distances, ensuring precise alignment with factory axle flanges and firewall patterns.
