What size bolts for Honda calipers?
For most Honda models, the front brake caliper mounting bolts are M12-based, typically around 25–32 mm long, while rear caliper bolts vary by model and can be M10 or M12. Always verify the exact size and torque in your vehicle’s service manual or by inspecting the existing hardware.
Front Caliper Mounting Bolts
Common Honda front caliper mounting bolt characteristics span a range of models; exact sizes can vary by year and trim. The following outline reflects typical configurations found on many recent Hondas.
- Thread size: commonly M12; pitch can be 1.25, 1.5, or 1.75 depending on the model/year.
- Length: typically about 25–32 mm, with some variants up to 34–40 mm on certain configurations.
- Grade: high-tensile bolts (roughly equivalent to grade 10.9 or higher) as specified by Honda.
Conclusion: Front caliper mounting bolts are generally M12-based across many Honda models, but exact thread pitch and length vary. Check the service manual or measure the bolt to confirm the correct size for your vehicle.
Rear Caliper Mounting Bolts
Rear caliper mounting bolts show more variation between models, particularly depending on whether the car is an all-wheel drive, a sedan, or a crossover. The following ranges cover common possibilities.
- Thread size: commonly M10 or M12, with pitches typically 1.25 (M10) or 1.25–1.75 (M12) depending on the model/year.
- Length: commonly 20–30 mm, though some rear setups may use longer bolts if the caliper sits farther from the bracket.
- Grade: high-tensile bolts, as specified by Honda for safe braking performance.
Conclusion: Rear caliper bolts can be M10 or M12 depending on the exact model/year. Always verify with the parts diagram for your vehicle or consult the service manual.
Additional notes on caliper hardware
Other brake hardware associated with calipers, such as guide pins/slider bolts and bracket bolts, have their own sizes. When replacing hardware, use OEM parts or high-tensile equivalents and reference the service manual for the correct torque specs and installation procedures.
How to verify the correct bolt size for your Honda
Practical steps to ensure you use the right bolts for your specific model/year:
- Consult the owner’s manual or official service manual for model-specific sizes and torque specs.
- Inspect the bolts on your vehicle to match thread diameter, pitch, and length, or bring one to an auto parts store for an exact match.
- Order OEM caliper mounting bolts for your exact model and year to ensure compatibility and safety.
Install with the torque values specified by Honda for your vehicle and use proper general brake hardware practices.
Summary
In short, Honda caliper bolts are not universal across all models. Front caliper mounting bolts are typically based on an M12 diameter with varying pitches and lengths, while rear caliper bolts range from M10 to M12 with lengths tailored to the model. Always verify the precise size, pitch, length, and torque from your model’s service manual or OEM parts diagram, and replace any worn or damaged hardware with the appropriate high-tensile fasteners.
What size is the bolt on a Honda caliper?
M10 x 80.3mm (3.16") - 14mm hex head.
What size is a brake caliper bolt?
There is no single universal size for brake caliper bolts; they vary by vehicle, so you must confirm the size for your specific make and model. For example, some vehicles use an M12 x 1.50 x 65mm bolt, while others might use a 7/16-inch fine thread or an M14-2.0 bolt. Common sizes can include M10, M12, or M14, with various lengths and thread pitches depending on the application.
How to find the correct size
- Check your vehicle's manual: Your owner's manual may have a list of specifications or can point you toward the correct part number.
- Use a parts catalog: Use an online or physical auto parts catalog by entering your vehicle's year, make, and model to find the correct part number. Sites like O'Reilly Auto Parts or even parts listings for specific makes like Toyota or Volkswagen can provide detailed specifications.
- Inspect the old bolt: If you have the original bolt, measure its diameter, length, and thread pitch (threads per inch or metric pitch).
- Count the threads: For a quick check, you can manually count the number of threads within a given length to find the thread pitch.
- Consult a professional: If you are unsure, a professional mechanic can accurately identify the correct size and grade for your vehicle.
Common sizes and examples
- M12 x 1.50 x 65mm: Used on the rear caliper bracket mounting bolt for some Volkswagen Jettas.
- 7/16" Fine Thread: Used on some GM caliper bracket brake bolts.
- M14-2.0: A common brake caliper bracket bolt size, often with an 18mm hex head.
- M12-1.25: Another common size for brake caliper bracket bolts, often around 46mm or 40mm in length.

What size bolts does Honda use?
For example, the most common metric thread sizes of Honda bolts are M12x1. 5mm and M14x1. 5mm. A M12 means the width of the thread area and a 1.5mm means the thread pitch.
