Q/Q+ Classification | Q+ (modern, higher performance) | Q (classic, lighter-duty) |
Compatibility | Fits 4707 style brake shoes | Fits 4515 shoes |
Cost | Usually higher | Usually lower |
The thickness of the lining is not the same. The 4707 brake lining is 4.8 mm thick. The 4515 brake lining is 4.6 mm thick. This small change matters when you put in the brake pad. If you use the wrong thickness, your brakes may not work well or wear out fast.
You need the right rivet pattern to mount the brake lining. The 4707 style brake shoes use a special rivet layout for their flat web. The 4515 brake lining has a different pattern because of the hump. Always check the rivet holes before you put in the lining. If you mix up the patterns, the brake pad will not fit right. This could hurt your brake system.
Different brands give different warranty terms. For example, the 4707 brake lining often has a 3-Year/300,000-Mile warranty for rust jacking. The 4515 brake lining usually does not have this warranty. You should read the warranty rules before you buy:
Model | Warranty Terms |
|---|---|
4707 | 3-Year/300,000-Mile warranty against rust jacking |
4515 | N/A |
The warranty replaces all other promises.
There is no promise that it will work for every use.
The seller is not responsible for extra damages.
How hot or wet it is can change how brake lining works. You need to match the friction code to how you drive. The table below shows common friction codes and their temperature ranges:
Friction Code | Temperature Range (°F) | Performance Description |
|---|---|---|
E | 200 - 400 | Moderate friction; smoother and quieter, common in lighter or line-haul service. |
F | 400 - 650 | Standard heavy-duty friction; balanced torque output and heat resistance for most regional and on-highway applications. |
G | 400 - 650 | High friction; designed for severe-duty, high-temperature, or downhill-grade service where maximum fade resistance is needed. |
Tip: Always check the shape, thickness, and rivet pattern before you put in a brake lining. This helps you avoid mistakes and keeps your vehicle safe.
This comparison helps you pick fast. If you drive a modern truck or want better performance, the 4707 style brake shoes and their brake lining are a good choice. If you drive a lighter vehicle, the 4515 brake lining may work for you and cost less.
You cannot swap a 4707 brake lining with a 4515 brake lining. The rivet patterns do not match. The lining thickness changes how the brake pad fits. The 4707 style brake shoes use a Q+ classification. The 4515 style brake shoes use a Q classification. If you try to use the wrong brake lining, the brake pad will not sit right. This mistake can cause poor braking and faster wear. Always check the shape and rivet holes before you install a brake pad.
You see the 4707 style brake shoes on modern heavy trucks. These trucks need strong brakes for long hauls and heavy loads. The 4515 style brake shoes work best on lighter vehicles. You find them on older trucks or trailers that do not carry as much weight. The axle position matters too. Most fleets use 4707 style brake shoes on drive axles. You use 4515 style brake shoes on trailer axles or lighter-duty positions.
Here is a quick list to help you remember:
4707 style brake shoes: heavy-duty trucks, drive axles, high-load cycles
4515 style brake shoes: lighter vehicles, trailer axles, low-load cycles
The performance of each brake lining changes with the duty cycle. The 4707 brake lining gives you higher friction and better thermal stability. You can trust it for repeated heavy loads. The 4515 brake lining works well in cold weather and light-duty cycles. It may fade if you push it too hard in high temperatures.
Here is a table that shows the performance differences:
Brake Lining | Duty Cycle | Friction Coefficient | Thermal Stability | Performance Issues |
|---|---|---|---|---|
4707 | Heavy-Duty | Higher | Better | Suitable for repeated high-load cycles |
4515 | Light-Duty | Lower | Lower | Cold-weather responsiveness prioritized, potential fade at high temperatures |
Note: If you drive a heavy truck, you need a brake lining that can handle heat and stress. If you drive a lighter vehicle, you want a brake pad that responds well in cold weather.
You must match the brake lining to your vehicle and driving needs. This choice keeps your brakes safe and helps them last longer.
You can spot the difference between 4707 and 4515 brake linings by looking at their shape and rivet patterns. The 4707 brake lining has a flat web. The 4515 brake lining shows a hump on the web. This hump stands out and helps you tell them apart quickly. When you check the rivet holes, you see that the patterns do not match. The 4707 lining uses a unique layout for its flat web. The 4515 lining has a different pattern because of the hump. If you look closely, you notice the thickness changes too. The 4707 lining is a bit thicker than the 4515. These are the main identifying features of 4515 and 4707 brake linings.
Tip: Always check for the hump on the web and the rivet pattern before you install a brake lining. This helps you avoid mistakes and keeps your brakes working safely.
You can use part numbers and manufacturer markings for brake shoe identification. These numbers help you find the right lining for your vehicle. Manufacturers print or stamp part numbers on the lining. You may also see brand names and other codes. These markings show the drum size, width, and position. They help you match the lining to your brake system.
Here is a table that shows how part numbers and markings help you identify brake linings:
Brake Lining | Brand | Drum Size | Width | Webs | Position | Applications |
|---|---|---|---|---|---|---|
4707 | Meritor/Spicer | 16.5 | 7 | 2 | Drive and Trailer | Meritor Q Plus, Spicer XL II, Meritor H.D. |
4515 | Meritor | 16.7 | 7 | 2 | Universal | Meritor Cast Iron |
You should always check the part number and brand before you buy or install a brake lining. This step helps you avoid using the wrong part. If you cannot find the marking, ask your supplier or check the manufacturer’s catalog.
Note: Matching the part number and brand ensures you get the right brake lining for your vehicle and keeps your brake system safe.
You need to look at several factors before you pick a brake pad for your vehicle. The type of vehicle matters most. Heavy trucks need a brake pad that can handle high loads and heat. Lighter vehicles work best with pads made for low-duty cycles. Regulations also play a big role. Some states require certain friction codes or lining thickness. You must check these rules to stay safe and legal.
Performance needs change from one driver to another. If you drive long distances or carry heavy loads, you want a brake pad with high thermal stability. If you drive in cold weather or haul light loads, you need a pad that responds quickly. Cost is another factor. You may want to save money, but cheap pads can wear out fast or cause safety issues.
Here is a table to help you compare:
Factor | What to Check |
|---|---|
Vehicle Type | Truck, trailer, or bus |
Regulations | State laws, friction codes |
Performance | Duty cycle, heat resistance |
Cost | Price, warranty, lifespan |
Tip: Always match the brake pad to your vehicle and driving needs. This keeps you safe and helps your brakes last longer.
You can make mistakes if you do not pay attention. One common mistake is using the wrong brake pad for your brake system. If you install a pad with the wrong rivet pattern or thickness, it will not fit right. This can cause poor braking or fast wear. Another mistake is ignoring the duty cycle. If you use a light-duty pad on a heavy truck, the pad may fade or fail.
Some people forget to check regulations. You must follow state laws and industry standards. Skipping this step can lead to fines or unsafe brakes. You may also overlook the warranty. If you buy a pad without a good warranty, you risk extra costs later.
Note: Always check the shape, thickness, and part number before you install a brake lining. This helps you avoid costly errors and keeps your vehicle safe.
