Dodge B350 Disc Brake Caliper Guide (1981-1994): Symptoms and Replacement
Is your heavy-duty Dodge van pulling to one side or are the brakes dragging? It might be time for a new caliper.
- The most common failure for B350 calipers is seizing or sticking due to corrosion.
- Always inspect the flexible brake hose; a collapsed hose can mimic a failed caliper.
- New aftermarket calipers (like DFC) offer higher quality consistency than remanufactured options (like Cardone or BBB).
- It is critical to replace calipers in pairs to ensure even and safe braking.
Is Your Dodge B350 Brake Caliper Failing?
The brake calipers on the 1981-1994 Dodge B350 are robust, but they can fail over time, especially due to age and moisture. The most common failure is a seized or sticking caliper. This happens when the caliper piston or the slider pins corrode and can no longer move freely. Because these vans can sit for extended periods, rust and corrosion are a frequent problem.
A Note on Brake Hoses
Before you replace a caliper, always inspect the flexible rubber brake hose that connects to it. Over time, these hoses can deteriorate from the inside and collapse. This creates a one-way valve, trapping brake fluid pressure in the caliper and causing it to lock up, even after you release the brake pedal. A new caliper will have the exact same problem if the hose is bad. It is often a good idea to replace the flexible hoses when you replace the calipers.
Choosing the Right Aftermarket Caliper
For a vehicle of this age, finding new original equipment (OEM) calipers is nearly impossible. The market consists almost entirely of new aftermarket and remanufactured aftermarket parts. Both can be good options, but it's important to understand the difference.
Brand Tiers for Your B350
- New Aftermarket (Dynamic Friction): Brands like Dynamic Friction Company (DFC) offer completely new calipers. These are manufactured to match the original factory specifications for fit and function. User feedback suggests DFC provides good quality for the price, making them a reliable choice without the uncertainty of a remanufactured part. Since every component is new, there's less risk of issues from worn parts.
- Remanufactured Aftermarket (Cardone, BBB Industries): Remanufacturing is a common practice for calipers. Companies like Cardone and BBB Industries take original caliper cores, clean them, and rebuild them with new seals, boots, and other wear items. This can be a cost-effective option. However, quality can be inconsistent. Some users have reported receiving remanufactured calipers with cosmetic flaws, reused hardware, or incorrect assembly. While many remanufactured calipers work perfectly, there is a higher chance of getting a defective unit compared to a new one.
What is a Core Charge?
Remanufactured calipers often have a "core charge." This is a temporary deposit you pay when you buy the part. You get this deposit back when you return your old, worn-out caliper to the seller. This process allows the remanufacturers to maintain a supply of cores to rebuild.
Estimated Cost for a Dodge B350 Brake Caliper
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket | $39.65 - $118.58 |
| Remanufactured Aftermarket | $35 - $90 (plus a refundable core charge) |
| Shop Labor | $100 - $200 per caliper |
Frequently Asked Questions
Should I replace calipers in pairs?
Yes, it is highly recommended to replace brake calipers in pairs (both front calipers or both rear calipers at the same time). This ensures even braking performance and prevents the vehicle from pulling to one side. Since both calipers have been subjected to the same conditions, if one has failed, the other is likely not far behind.
What are the signs of a seized caliper?
Common signs include the van pulling to one side when braking or driving, a burning smell from the wheels after a drive, a wheel that is noticeably hotter than the others, and premature or uneven brake pad wear. You might also feel like the vehicle is sluggish or dragging.
Can I rebuild my own B350 caliper?
Yes, caliper rebuild kits are available. These kits typically include new piston seals and dust boots. Rebuilding requires completely disassembling the caliper, cleaning all corrosion from the piston and bore, and carefully reassembling it. For many owners, given the low cost of a complete new or remanufactured caliper, replacement is the faster and more reliable option.
Do I need special tools to replace a brake caliper?
You will need a standard set of mechanic's tools, including a socket set, wrenches, a breaker bar for stubborn bolts, and a C-clamp or piston compressor tool. You will also need tools for bleeding the brakes, which includes a clear hose and a container to catch old fluid. A torque wrench is essential for tightening bolts to the correct specification.
Technical Specifications
Varies by specific year and axle configuration (e.g., with or without ABS, different front axle weight ratings). Always verify the exact fit for your vehicle's specifications.
