Is Different Year Silverado Brake Caliper Bracket Bolt Size Different?

What is the Silverado brake caliper bracket bolt size? Unlike many other vehicles from different brands, Chevrolet Silverado’s all models feature almost the same bracket bolt size, which is 14mm x 2.00.

Yes, the company uses identical bolts for different Chevy Silverado trucks, but some riders claimed to utilize varied-sized bolts for their Chevy vehicles.

So, what do you think, is that a fact or tittle-tattle? Let’s find out the veracity concerning the caliper bracket bolt size through this blog post.

Silverado Brake Caliper Bracket Bolt Size: Take A Look At The Correct Size

All the Chevy Silverado models produced between 1999 and 2019 use a universal bolt size of about M14 x 2.00 x 37mm. Here thread size is M14 mm, pitch and length/ hex of the caliper bracket bolt are 2.0 and 37 mm.

Hence, if you are searching for a Silverado front brake caliper bracket bolt size or size of the rear mounting bolt, the answer is pretty straightforward: it’s the same for all caliper brackets of different year models.

But according to some users from the GM-Trucks forum, the 2006 Silverado brake caliper bracket bolt size, especially the Silverado 1500, is 17mm, which is basically the head size.

On the other hand, based on the data from the Silveradosierra forum users, the Chevy brake caliper bolt size for Silverado 1500 HD, 2500 & 2500 HD with eight lugs is M16 x 2.0 x 40 mm. That means this bolt is larger in width and length than the M14 one.

Again, one user from GM-Trucks has stated about using an M14 caliper bracket bolt for his 2006 Chevrolet Silverado 1500 wt. But this bolt is slightly shorter than its 37mm variation.

Lastly, some Silverado users say that the company sometimes uses either a 15mm or 18mm bolt depending upon the caliper bracket. However, a Chevy Silverado with a 15mm caliper bracket bolt is rare. And we haven’t found any evidence supporting the statement of using 15mm bolts on Silverado’s caliper brackets.

But it’s true that you can use the 7/16 or 3/8 size Allen wrench or the Torx to mount the caliper bracket bolts.

In case you need, you can check what year Silverado wheels are interchangeable and what they are.
