1. Power Stop K2293-360 Front Brake Kit: Best Overall
Power Stop’s K2293-360 is one of the most popular drum-to-disc conversion kits, designed for trucks and SUVs like the Ford F-150 and Chevy Silverado. In our evaluation, the drilled and slotted rotors provide consistent performance under heavy use, and the ceramic pads keep dust low. Based on owner feedback, the kit fits well with minimal modification, though some users noted that the calipers may require trimming on certain vehicles.
However, this kit is not a universal solution. It is vehicle-specific, so you must verify compatibility with your exact model and wheel size. Those with smaller wheels (15 inches or less) may need to upgrade their rims. It is also not ideal for pure off-road rigs where mud and debris can clog the drilled holes. Skip this if you want a budget option for a rare or older vehicle.
- Complete kit with zinc-coated rotors for corrosion resistance
- Ceramic pads produce low dust and quiet operation
- Direct fit for many Ford, Chevy, and Dodge applications
Pros: Excellent stopping power and fade resistance; All hardware included for straightforward installation
Cons: Not compatible with all wheel sizes (check clearance)
2. R1 Concepts Front Brake Kit: Best Value
R1 Concepts offers a cost-effective conversion kit that balances performance and affordability. The cross-drilled rotors help reduce brake fade, and the semi-metallic pads provide reliable stopping power. Based on the spec sheets, the kit includes remanufactured calipers that meet OEM standards. Owner feedback highlights the straightforward installation and significant improvement over drums.
However, the semi-metallic pads produce more dust and may squeal under light braking. This kit is best for daily drivers who want an upgrade without breaking the bank. If you prioritize quiet operation or have a performance vehicle, consider spending more for ceramic pads. Skip this if you need a kit for a rear axle, as it is primarily front-only.
- Cross-drilled rotors improve heat dissipation
- Semi-metallic pads offer strong bite when cold
- Comes with premium hardware and brake fluid
Pros: Great performance for the price; Easy bolt-on installation for many applications
Cons: Semi-metallic pads can be noisy and dusty
3. Wilwood Disc Brake Conversion Kit: Best Performance
Wilwood is renowned for high-performance braking, and their conversion kit is designed for classic cars, hot rods, and muscle cars. In our evaluation, the billet calipers and slotted rotors deliver superior heat management and stopping force. The adjustable proportioning valve allows fine-tuning of brake bias, which is critical for modified vehicles. Owner feedback from track enthusiasts praises the consistent pedal feel and fade resistance.
However, this kit is expensive and may require additional modifications like a dual master cylinder. It is not a simple bolt-on for most daily drivers. The pads also have a shorter lifespan under street use. Skip this if you are on a tight budget or want a hassle-free install for a stock vehicle.
- Billet aluminum calipers reduce weight
- Adjustable proportioning valve for custom brake bias
- High-temperature brake pads included
Pros: Exceptional stopping power for high-performance builds; High-quality materials and machining
Cons: Premium price; not a budget option
4. Dynacorn Rear Disc Brake Conversion Kit: Best for Classic Cars
Dynacorn’s rear conversion kit is tailored for classic GM A-body cars, making it a top choice for restorers. Based on manufacturer specs, it includes everything needed to convert the rear drums to discs while keeping the parking brake. Owner feedback indicates a straightforward installation with minimal cutting or welding. The kit uses high-quality cast iron calipers that match the original look.
However, this kit is not universal; it only fits 1964-1972 GM A-bodies. If you have a different make or model, look elsewhere. Also, the rotors are solid (not drilled or slotted), so they may not handle extreme performance driving. Skip this if you want a kit for a modern truck or a non-GM classic.
- Includes new calipers, rotors, pads, and parking brake cables
- Retains factory parking brake function
- Direct fit for 10-bolt and 12-bolt rear ends
Pros: Preserves parking brake functionality; Bolt-on design for classic GM models
Cons: Limited to specific GM A-body applications
5. Jegs Front Disc Brake Conversion Kit: Best for Jeeps
Jegs offers a dedicated front disc brake conversion for Jeep CJ models, a popular upgrade for off-roaders. Based on owner reviews, the kit bolts on easily with common tools and provides much better stopping power than the original drums. The rotors and calipers are sourced from reputable suppliers, ensuring reliability on the trail.
However, the included brake lines are designed for stock ride height; lifted Jeeps may require longer lines. The pads are semi-metallic and can be noisy. Also, this kit only covers the front axle. If you need a rear conversion or have a Wrangler YJ or TJ, look for a different kit. Skip this if you want a complete four-wheel conversion.
- Includes rotors, calipers, pads, and brake lines
- Bolt-on installation with no axle modification
- Improves stopping power over stock drums
Pros: Simple installation for Jeep CJ owners; Significant braking improvement off-road
Cons: Brake lines may be too short for lifted Jeeps
6. SSBC (Stainless Steel Brakes) Conversion Kit: Premium Build
SSBC is known for premium brake components, and their conversion kit for the Ford Mustang (1965-1973) is a top-tier option. The stainless steel calipers are a standout feature, offering superior durability and corrosion protection. In our evaluation, the slotted rotors and high-temp pads provide consistent stopping power even under aggressive driving. Owner feedback highlights the improved pedal feel and confidence on the road.
However, this kit comes at a premium price, making it less accessible for budget-conscious buyers. It is also vehicle-specific; ensure compatibility with your Mustang model and year. The installation may require some mechanical experience, particularly with brake line routing. Skip this if you do not own a classic Mustang or want a more affordable option.
- Stainless steel calipers resist corrosion
- Slotted rotors reduce gas buildup
- Includes all necessary hardware and instructions
Pros: Long-lasting corrosion resistance; Excellent fade resistance for street and track
Cons: High cost compared to alternatives
7. Leed Brakes Front Disc Brake Conversion Kit: Budget Pick
Leed Brakes offers an affordable conversion kit aimed at off-roaders with Dana axles. Based on owner feedback, the kit can significantly improve braking over drums, but installation may require some grinding or shimming to achieve proper alignment. The components are functional but not as refined as higher-priced options. The rotors are solid and the pads are semi-metallic.
However, the durability is questionable; some users reported premature wear or rust on the rotors. Brake lines are not included, so you will need to source those separately. This kit is best for budget-conscious builders who are willing to do some extra work. Skip this if you want a hassle-free, long-lasting solution or if you are not experienced with mechanical modifications.
- Includes rotors, calipers, pads, and mounting brackets
- Compatible with Dana 30, 44, and 60 axles
- Budget-friendly alternative to name brands
Pros: Lowest price point in this guide; Wide compatibility with Dana axles
Cons: Some owners report fitment issues requiring modification
Frequently Asked Questions
What vehicles can benefit from a drum to disc conversion?
Any vehicle originally equipped with drum brakes can benefit, especially older trucks, SUVs, and classic cars. Drum brakes are prone to fade under heavy use and require more maintenance. Disc brakes offer better stopping power, heat dissipation, and easier service. Common candidates include Ford F-150s, Chevy Silverados, Jeep CJs, and classic Mustangs.
Is a drum to disc conversion difficult to install?
Difficulty varies by vehicle and kit. Many kits are designed as bolt-on replacements, but some may require modifications like trimming dust shields, bending brake lines, or installing a proportioning valve. Basic mechanical skills and tools are usually sufficient. We recommend following the manufacturer’s instructions and consulting a professional if unsure.
Do I need to replace the master cylinder or proportioning valve?
Often yes. Disc brakes require more fluid volume and different pressure than drums. Many conversion kits include a proportioning valve, but you may also need to upgrade the master cylinder to one with a larger bore. Check the kit specifications and vehicle requirements. Some kits are designed to work with the stock master cylinder, but performance may be compromised.
Will my parking brake still work after conversion?
It depends on the kit. Some rear conversion kits include parking brake cables and mechanisms that integrate with the disc calipers. However, many front-only conversions do not affect the parking brake. If you need a parking brake, look for a kit that specifically mentions it, like the Dynacorn kit for GM A-bodies.
How much does a drum to disc conversion kit cost?
Prices vary widely based on brand, vehicle fitment, and included components. Budget kits can be found at lower price points, while premium kits with stainless steel calipers or for high-performance applications cost more. We recommend balancing cost with quality and ensuring the kit includes all necessary parts to avoid additional expenses.
Our Verdict
After researching and comparing the top options, the Power Stop K2293-360 stands out as the best overall choice for most trucks and SUVs due to its complete package, performance, and ease of installation. For those on a budget, the R1 Concepts kit offers excellent value without major compromises. Always verify compatibility with your specific vehicle before purchasing.
