When changing the entire brake, you need to know the torque specs for brake caliper bracket bolts.
Brake pads, rotors, and calipers are common wear components on all vehicles and are crucial for ceasing the vehicle as it operates.
When these elements are overlooked with a shortage of braking material or improper installation, it may result in catastrophic consequences.
You will need the technical knowledge to install the caliper bracket properly to avoid any potential accidents.
Worry not; the article will guide you in doing so.
What Is a Brake Caliper?
A caliper is a disc brake component that most automobiles use for their front brakes. The brake caliper stores your car’s pistons and brake pads.
Its purpose is to slow the automobile’s wheels by causing friction through the braking rotors.
After you push the brakes, it will act as a clamp on the rotor, preventing the wheel from rotating. There are metal plates called brake pads within each caliper.
Once you hit the pedal, the fluid exerts pressure upon the pistons in the caliper, causing the pads to press on the brake rotor, which will help slow the vehicle.
What Is The Torque Specs For Brake Caliper Bracket Bolts
Based on driving behavior and vehicle type, brakes should last around 20,000 to 35,000 miles. They still need to change at some points.
However, you will need mechanical knowledge and the brake torque spec for caliper bracket bolts.
If the bolts come loose or tight, there will be many problems later. Different cars will need you to tighten the caliper bolts to a certain extent.
ASE-certified mechanics also prepare an informative guide. You can follow them and get the bolts tightened properly for your safety.
According to ASE-certified instructions, when installing the mounting bracket bolts, the brake caliper torque specs should be between 70 and 90-foot pounds.
Besides, tighten the two mounting bolts with a caliper bracket bolt torque of 35 to 45 foot-pounds when you install the caliper over the pads and slides.
How Are Brake Calipers Connected to the Rest of the Braking System?
Rotors, brake pads, and calipers are common wear items and are important to halting the vehicle. Replacing the whole brake system will be difficult, and you should leave it to a technician.
However, the caliper assembly instruction below will guide you to check the calipers in case of an emergency.
How To Remove the Caliper Mounting Bracket
First, find the sliding bolts or caliper mounting on the interior of the caliper and unscrew them. In most situations, the fit brake caliper bolt sizes are 18mm, 15mm, 14 mm, a 35 Torx bit, or 10mm hex drive.
Some Volkswagens utilize their own specialized 14mm ten-point Torx to prevent you from removing the brakes with the correct tools. It would help if you had a particular tool for the task.
Twist and remove the bolts by rotating them counterclockwise with a compact torque wrench or a ratchet.
An extra wrench may be required to prevent the slide from spinning, but this is not common. Once detached, check the threads for wear and substitute them if necessary.
The caliper is now loosened. Hold it and pull it away from the brake caliper mounting bracket and the pads.
If not fully retracted, you can gently shake it to release it. Avoid kinking, bending, or allowing the entire caliper to dangle from the flex hose.
Check the brake hose and brake caliper for chafing, leaks, and cracks, and replace them when needed.
How To Reinstall Bolts With Correct Torque Specs For Caliper Mounting Bracket
Twist the caliper slides to the caliper mounting bracket, ensuring the slides go freely in or out. Otherwise, detach the slide for further examination.
They can become rusty and develop grooves. If it is the case, they must be changed, or it will result in unbalanced pad wear.
Wipe the bolts’ threads with a tiny wire brush before restoring the caliper mounting bracket. Then, by hand, insert two mounting bolts into the caliper housing bracket.
Screw the bolts properly to the manufacturer’s brake caliper bolt torque spec, around 70 to 90 foot-pounds. To keep the bolts from coming free, use some thread lock.
What Are Common Loose Caliper Bolt Symptoms
If the brake calipers aren’t performing as they should, there are certain visible warning signs that you should look out for. Let’s take a look at the indications of improper torque specs for caliper bolts.
Pulling To One Side
When one of the calipers is functioning, but the other is just not, your car will pull to one side as you use the brakes.
When you break, you may be forced to the next traffic lane, potentially resulting in an accident.
Spongy Or Soft Brake Pedal
When the brake caliper has a hole, you will feel like you are driving in a wipe when you step on the brakes. People prefer it as a soft brake pedal.
It means the water-driven pressuring component is no longer in the framework, and there is a liquid leakage elsewhere.
You may also experience this situation if a cylinder in your caliper is seized. It is because it causes a larger gap between the rotor and the cushion, requiring you to press more to make it operate.
Leaking Fluid
Another loose caliper bolt symptom is liquid leaking from your calipers. You will find liquid spills when there is a loose bleeder screw in the caliper.
Liquid can start leaking around any cylinder. To check the issue, you can look around the wheels to determine if it is a problem.
Uneven Brake Pad Wear
If there is a loose caliper bolt, the calipers aren’t working properly, resulting in uneven wear in the brake pads. One will wear far faster while the other remains, reducing your overall driving performance.
The pads will be applied insufficiently, causing them to drag over the rotor. The staying caliper slide pins will cause lopsided brake pad wear.
Dragging
If the brake calipers get stuck while you engage your brake, you will notice that the car cannot go in the way it needs to.
Therefore, you’ll always have the dragging sensation when you hit the brakes to try to come to a stop.
Grinding Sounds
Because the brake pads will wear out as a result of a trapped brake caliper, drivers will hear the different sound that comes with a worn-out pad.
It’s not screaming but a crushing wheel bearing noise to warn you that the brake pads are worn out.
What To Do If You Have A Bad Brake Caliper?
You will never want to bet your life on the brakes, right? That’s all there is to it. A seized or stuck caliper bolt might result in a partial or total loss of braking ability.
When you see the above symptoms, there should be an inspection, and the least common repairs are needed.
Also, you would overhear a few people discussing advancing brake calipers. However, it is the twenty-first century, and replaceable calipers are plentiful—nobody upgrades them anymore.
Simply replace the caliper. It’s a lot easier.
In case you are unable to replace the caliper, have a professional complete the job for you. You’d rather not gamble with your brakes in the long run.
How Much Does It Cost To Replace Loose Calipers?
Considering all factors, a brake caliper replacement on your car might take you a substantial sum of money.
Depending on the brand and type of vehicle, you might end up paying around $350 to $800 to buy your rotors, cushions, and calipers.
The average cost of a brake caliper replacement is between $724 and $1,442. Labor expenses are estimated to be from $94 to $120.
You can say that replacing a brake is pricey. However, we all know that calipers need replacing. This is a procedure you must never ignore or put off for an extended period.
It is an important part of your car’s protection. You might endanger yourself and others if you don’t have them repaired when they’re not operating.
Conclusion
The torque specs for brake caliper bracket bolts are 70 to 90-foot pounds, based on ASE-certified mechanics instructions.
However, different cars will need you to tighten the bolts to various specifications. If you are unsure when reading the manual, you should take it to some experts for safety.
