By following the tips and guidelines in this guide, you can make informed decisions when it comes to selecting the right brake calipers for your vehicle.
Understanding Brake Calipers Types
There are two main types of brake calipers: Floating and Fixed.
Floating Calipers
Floating calipers have pistons on only one side of the caliper, which allows the caliper to move sideways. When the brakes are applied, the caliper pushes against the inner brake pad, causing it to clamp down on the rotor. This design is simpler and lighter, but may not provide as consistent braking performance as fixed calipers.
Fixed Calipers
Fixed calipers have pistons on both sides of the caliper, which means they do not move when the brakes are applied. This design provides more consistent braking performance, as the caliper applies pressure evenly on both sides of the rotor. Fixed calipers are usually found on performance vehicles due to their superior braking capabilities.
Measuring Brake Caliper Mounting Points
When it comes to determining the correct size of brake caliper for your vehicle, one of the most crucial steps is measuring the mounting points. This will ensure that the caliper fits properly and functions as intended.
Start by measuring the distance between the mounting holes on the caliper. Use a caliper or ruler to get an accurate measurement in millimeters. Make sure to measure from the center of one hole to the center of the other for precision.
Checking Bolt Hole Spacing
Next, measure the distance between the two mounting holes on the brake rotor. This will help you ensure that the caliper aligns properly with the rotor and that the brake pads make even contact. Again, measure from the center of one hole to the center of the other for accuracy.
Choosing the Right Brake Caliper Size for Your Vehicle
When it comes to choosing the right brake caliper size for your vehicle, there are several factors to consider. The size of the brake caliper will affect the overall braking performance of your vehicle, so it is important to choose the correct size based on your specific needs.
Factors to Consider
One of the main factors to consider when choosing a brake caliper size is the size of your vehicle’s wheels. Larger wheels may require larger brake calipers to provide adequate braking power. Additionally, the weight of your vehicle and the type of driving you do will also impact the size of brake caliper you need.
Brake Caliper Sizing Chart
| Vehicle Size | Wheel Size | Recommended Caliper Size |
|---|---|---|
| Small | 13-16 inches | 6-8 inches |
| Medium | 17-19 inches | 8-10 inches |
| Large | 20+ inches | 10+ inches |
Use this sizing chart as a guide to help you choose the right brake caliper size for your vehicle. It is always best to consult with a professional mechanic or brake specialist to ensure you are selecting the correct size for your specific vehicle and driving needs.

Common Mistakes to Avoid When Sizing Brake Calipers
When sizing brake calipers, it’s important to avoid common mistakes that can lead to improper fitment and potentially dangerous situations. Here are some key errors to steer clear of:
1. Ignoring Rotor Size
One common mistake is failing to consider the size of your rotors when selecting brake calipers. It’s essential to ensure that the calipers you choose are compatible with the diameter of your rotors to maintain proper braking performance.
2. Overlooking Clearance Issues
Another mistake to avoid is overlooking clearance issues. Make sure to check for any potential clearance problems with your wheels, suspension components, or other parts of your vehicle that could affect the fitment of your brake calipers.
- Ensure that the calipers you select are not too large or too small for your specific vehicle.
- Double-check measurements and fitment guides to prevent clearance issues.
Comparing Fixed vs. Floating Calipers
Fixed Calipers: Fixed calipers have pistons on both sides of the rotor and remain stationary in relation to the rotor. They provide better braking performance and are less prone to flexing under high-pressure braking.
Floating Calipers: Floating calipers have pistons on only one side of the rotor and are able to move laterally to apply pressure. While they are easier and cheaper to manufacture, they are not as effective at distributing pressure evenly.
When choosing between fixed and floating calipers, consider your driving style and performance needs. Fixed calipers are ideal for high-performance vehicles or racing applications, while floating calipers are more suitable for everyday driving.
Factors to Consider When Selecting Brake Rotors Alongside Calipers
When selecting brake rotors alongside calipers, there are several important factors to consider to ensure optimal performance and safety:
