Brake caliper bolts are also known as caliper brackets too since they attach to that part of the brake caliper referred to as the bracket.

These bolts also hold the brake caliper firmly to either the spindle or the steering knuckle. Ideally, you will be supplied with 2 slider pins and 2 bolts that will attach the caliper to the caliper bracket, but not the bolts for the bracket which are connected to the chassis.

These bolts are generally regarded as a sort of brake hardware package which is likely to cost a little more. Should you get landed with corroded bolts, you can use steel wool or grease to get them sliding once again. 

No, brake caliper bolts are not reverse threaded. Previously, reverse threading was ominously used when the normal rotation of brake parts or other implements would loosen fasteners.

Sometimes, however, they usually feature on pulleys and idler bolts as well as lug nuts among others. Expectedly, there is just not any benefit accruing to a non-spinning part such as calipers.

What happens to the coinage ‘ Rightie, Tightie and Leftie, Loosie?’ It simply means turning counterclockwise loosens, while turning clockwise tightens.

Generally, all nuts and bolts which are cut with the left-hand threads operate in the opposite direction.

 Also, the bolts that maintain the calipers in place are of the same size, and if you should put brake pads backward, there is the possibility that serious damage may occur.

This damage can destroy the pads and possibly the rotors and calipers too, apart from reducing the effectiveness of the brake entirely.

Like all other fasteners, brake caliper bolts are best when they are removed and installed properly.  Although caliper bolts may not be reversely threaded, your user manual could be of tremendous help with this.

Generally, reverse threading is utilized whenever normal rotation loosens the fasteners. Therefore, sometimes, these bolts are used on pulleys and idler bolts or even lug nuts among many others.  However, there is not any benefit of a non-spinning part like the brake calipers.

What are brake calipers bolt reverse?

Brake calipers reverse threading is utilized mainly in situations where the normal rotation would loosen the fasteners.

As a result of this, sometimes, they are used in such devices as pulleys, idler bolts, and lug nuts, although there are no benefits on any non-spinning components such as calipers.

For brake calipers to work as expected,  they should be installed and removed correctly.

Consequently, some brake caliper bolts are reverse threaded, and most nuts/ bolts that are usually cut with the left-hand threads work in a reverse way.

You should make sure to clean the caliper guide pins on all floating calipers in a solvent before you apply great during both the installation and removal of your brake calipers.

The grease used will likely be exposed to extreme heat and pressure too. Therefore, you should always use only caliper-specific grease on them.

 The general rule of the thumb is never to put a torn bolt back on again. It is possible to put brake calipers on the wrong side in some vehicles.

And since you can’t bleed off the air which gathers at the top of the calipers, and the bleeder screw can be at the bottom, it is still not likely to give you a firm brake pedal when braking the vehicle.

Right hand leading calipers mount on the right side of the vehicle at the front end of the brake rotor. On the other hand, most right-hand trailing calipers usually mount on the rear edge of the brake rotors.

Bores that are of equal sizes,  which are mostly fitted on calipers of the same sizes on all 4  pistons can be mounted in any of the ways you prefer without any problems. 

Commonly, factory engineers and aftermarket brake-swap kits are known to place the calipers (whether leading or trailing) to ensure that the bleed screws end up in approximately the 12: 00 position to prevent trapping any air and also to achieve maximum brake cooling effect, while at the same time not obstructing either the suspension or body panels.

On the disc brakes of most vehicles, there is a rear brake caliper. Brake calipers are also known to fit around the rotors of the vehicle, which can either slow down or stop the vehicle when they squeeze the brake pads against their rotors thereby causing immense friction. Many cars are fitted with floating or fixed calipers.

Why are brake caliper bolts reverse threaded?

Ideally, caliper brackets are very specific since a right caliper is placed on the right wheel and the left also on the corresponding wheel too.

Brake caliper bolts, like most fasteners, work very satisfactorily whenever they are removed and installed correctly. Although the ‘left-loosens while the right tightens mechanism is mostly preferred, there are still brakes that have reverse threaded caliper bolts.

They are used whenever normal rotation is likely to loosen the fasteners. As a result of this, they are commonly utilized in pulleys, idler bolts, and so on.

However, there is still no known benefit when they are used on any non-spinning part like the calipers. Therefore, caliper bolts are reversely threaded mainly when normal rotation is expected to loosen the fasteners.

Can I thread a brake caliper bolt reverse?

Although caliper bolts are hardly reverse threaded, you can do so when you want normal rotation of the bolt to loosen the fasteners.

This is the reason why they are mainly fitted in such devices as pulleys, lug nuts, and idler bolts. Furthermore, there has yet to be identified any known benefit when they are used on non-spinning equipment like the calipers.

Caliper bolts are also known to work better mostly when they are both removed and installed correctly. However, although the left looses and the right tightens mechanism is preferred, some bolt calipers are still reverse threaded, but your vehicle’s user manual will have more explanation on the matter.

In addition, all caliper bolts that hold the calipers in position are of the same size, which can easily be confused with the caliper brackets even though they are of different sizes.

Generally, caliper bolts have different part numbers according to the user manuals. However, the right tightens while the left loosens mechanism still holds in brake caliper bolts.

In other words, you tighten them when you turn clockwise and loosen them when you turn counterclockwise.

Yes, you can thread a brake caliper bolt reverse, even though it is not known whether that has been done previously or it has any benefit.

How do I thread a brake caliper bolt reverse?

Reverse threading a bolt caliper involves a couple of diligent steps. 

Step 1

First, you should correctly remove the brake caliper bolts. If you find doing this difficult, you can use any top-quality penetrating oil to clear away rust on the bolt.

This should be done after allowing it to soak in the fluid for a few minutes before you remove the bolt in the correct direction.

Step 2

Here, you should inspect the bolt and its hole on the spindle. Afterward, you should also remove all the parts that need replacing carefully.

Step 3

Then, you should use a good thread cleaner or thread chaser to rethread the holes of the bolts.

Step 4

Make sure to install all the new brake system components after you have ascertained that both the caliper bolts and the bolt holes on the spindle are in perfect conditions.

Make sure that the new threads have thread-locker applied on them before you slowly guide the brake caliper bolt into the corresponding spindle.

Step 5

You should use any recommended torque pressure to tighten the brake caliper bolts.

Which way does brake caliper bolt reverse thread?

Generally, caliper bolt reverse thread involves turning right to tighten and left to loosen. In other words, turning the bolts counterclockwise loosens them while clockwise turning tightens them.

Mostly, nuts and bolts that are cut using left-hand threads operate differently.

Are all caliper bolts the same?

Yes, some caliper bolts are the same although others still differ. However, you should be careful not to confuse them with caliper brackets which are of different sizes.

In addition, caliper bolts also have the same part numbers according to their user manuals.

Are Brake Caliper Bolts Reverse Threaded – Conclusion

Generally, caliper bolts are not reverse threaded although they can be for certain specific reasons. Brake calipers along with rotors and pads are an integral part of the brake system, which is used to slow down the car.

For their importance in safe driving, you are strongly advised not to take brake issues for granted. On the other hand, you should choose and use them carefully through effective and regular maintenance.

For reasons of safety, their installation is of paramount importance also, and this is where caliper bolts should be treated with respect.

You are advised to carefully study how the caliper bolts are threaded, screwed, or unscrewed onto the brake system. The user manual is a very reliable reference for all these requirements.
