Even though your brake pedals are really hard to press, don’t freak out! You have a few options for resolving the problem and getting your vehicle back on the road. Here we’ll look at some of the most prevalent causes and solutions for brake pedal hardness and brake locking.
While a lack of fluid in the master cylinder is the most typical reason of a harsh brake pedal, air in the lines or worn out brake pads can also be to blame. Preventing all of these problems is as simple as performing routine maintenance and consulting the owner’s manual provided by your vehicle’s manufacturer.

To help you out if you’re having issues with your brakes, here are some tips.
How Does Braking Work?
There are two primary types of braking systems: disc brakes and drum brakes.
hydraulics and mechanicals both apply. Instead than using a cable or a rod to pull brake pads back into place when they get too far away from their original position, hydraulic brake systems use fluid pressure to do so.
Due to its greater efficiency and reliability, hydraulics are the most popular type in modern automobiles (although some older vehicles still have mechanical ones).
There is a good probability that one of these parts has failed if your brake pedal is hard or locks up while driving.
The master cylinder is in charge of determining how much force is sent via each line.
Brakes can lock up if there aren’t enough fluids in the system, or if the brake pads wear down, it will be more difficult to stop the automobile.
What Causes Brake Pedals To Go Hard?
There are a number of reasons why your brake pedal may feel sluggish or even completely jammed. Among them are:
- the master cylinder is too low on fluid (possibly because of leaks)
- there’s air in one of its lines
- and/or it has worn out over time from use
There are less common causes of brake pedal problems, such as a seized caliper or corroded lines, but these can nevertheless occur. You should have your brakes checked out by a professional if you’re experiencing problems.
What Causes Brakes To Lock Up?
Brakes locking up can be caused by a variety of things. Among them are:
- a seized brake caliper (this is what squeezes the brake pads against the rotor)
- worn-out brake pads that can’t create enough friction to stop the car in time; and/or
- an issue with the ABS system (Anti-lock Braking System), which prevents wheels from locking up and keeps you in control of the car during a panic stop.
Hard Braking While Driving
If your brakes are locking up or being firm, it’s possible that the pedal isn’t to blame.
There may be other issues with your automobile, such as worn out brake pads or rotors, that could cause your brake system to lock up at high speeds and cause an accident if left unchecked.
How To Fix Brake Pedal Hardness And Locking Up
There are several things you can do if your brake pedal is too hard or locks up:
- Check fluid levels in the master cylinder and refill as needed.
- Inspect brake pads for wear and replace if necessary.
- Bleed hydraulic system (consult a mechanic if you’re not comfortable doing this yourself).
- Adjust braking pressure by turning screws on the master cylinder (again, consult a mechanic if you’re not familiar with how to do this).
- Replace the master cylinder or any other component that might be causing problems in the braking system.
Symptoms Of Brake Problems
Other than squeaky brakes and a seized-up transmission, you should consult a professional technician if you notice any other problems with your car. These could include, but are not limited to:
- Squeaking or grinding noises when braking;
- The vehicle pulls to one side when braking;
- The brake pedal feels “spongy” and doesn’t respond as quickly as it used to.
- If you’re experiencing any of these symptoms, then take your car in for a brake inspection right away! It’s always better to be safe than sorry, especially when it comes to something as important as your brakes. These can include:
- Squeaking or grinding noises when braking;
- The vehicle pulls to one side when braking;
- The brake pedal feels “spongy” and doesn’t respond as quickly as it used to.
If you see any of these signs, it’s time to get your brakes checked out.
As crucial as brakes are, it’s better to be safe than sorry.
Brake Fluid
It’s important to know that there are two kinds of brake fluid.
DOT-approved silicone and DOT-rated materials. For the most part, the former is the preferred choice; if you’re unsure whether your car requires it, consult your owner’s handbook.
In order to keep things operating properly, brake fluid must be updated on a regular basis (every two years or so). Corrosion can build on metal surfaces in the braking system, resulting in issues like hard pedals or locking up.

Performing the work yourself is an option if you are self-assured and motivated.
- Make sure that your car is parked on a level surface and that the engine is turned off;
- Locate the brake fluid reservoir – it’s usually found near the wheel well or under the hood;
- Remove the cap from the reservoir (be careful not to spill any fluid);
- Pour new brake fluid into the reservoir until it reaches the “full” line;
- Replace the cap securely and double-check that all connections are tight before starting your engine.
Bad Brake Pads
If your brake pads are worn out, the brakes will become jammed and the rotors will be damaged. Check for these indications to see whether your brake pads need to be replaced:
- The pad is thin and there’s a lot of metal showing
- There’s a deep groove in the pad
- The pad has been “squished” down so much that it’s touching the rotor.
Brake Bleeding
You may have air bubbles in your hydraulic system if your brake pedal is mushy and doesn’t respond promptly. Incorrectly changing your brake fluid or leaving the cover off of your brake fluid reservoir can cause this.
Because leaking brake fluid can cause corrosion and other issues if left untreated for too long, these lines running up to each wheel caliper or drum assembly should be repaired as soon as feasible.
How To Bleed Brakes?
Brake bleed is a simple task that most people can perform on their own using only a few basic tools:
- Park your car on a level surface and make sure that the engine is turned off;
- Locate the bleeder screw – it’s usually found near each wheel, either on top of or underneath;
- Attach one end of a piece of rubber tubing (about two feet long) overtop this screw and fit the other end over the open top of a container that’s large enough to hold brake fluid;
- Slowly loosen the screw until brake fluid starts flowing from the tubing (be careful not to let any air bubbles get in);
- Close the screw once all the old fluid has been drained and replace the tubing on the next wheel in line.
If you’re not sure how to properly bleed your brakes, see your owner’s manual. Depending on the model of car, a varied set of approaches may be necessary. If you don’t feel confident working on your automobile on your own, have it serviced by a professional mechanic.
How To Replace Worn Out Brake Pads?
If your brake pedal is firm or locks up, it’s time to get your car fixed up right away. Listed below are the actions you should take:
- Remove old pads from the caliper by unscrewing bolts holding them in place;
- Lubricate new pads before installing them into position on top of rotors (this will help prevent squeaking);
- Replace any washers that may have come loose during the removal process, and finally – Replace bolts securely so they don’t fall out again! If all else fails, consult a mechanic about what could be causing this issue (and how best to fix it)
Insufficient Vacuum
Your car should produce a vacuum when you depress the brake pedal. If this technique doesn’t produce enough pressure, it might cause issues like hard pedaling or locking up. Check with a mechanic to see if this is the cause of your problem (they’ll have all the necessary tools).

In order to do this repair, you’ll have to follow these steps:
- Locate and remove any defective parts from under the hood;
- Replace them with new ones from an auto parts store;
- Reconnect everything according to the manufacturer’s instructions so nothing gets damaged during installation! It may also help if you check around for leaks before proceeding any further. If all else fails, consult your mechanic about what could be causing this issue (and how best to fix it)
The Master Cylinder Is Leaking
The braking fluid and pressure are stored in the master cylinder, which is a component of the brake system. It’s possible to suffer severe braking or locking up troubles if these components aren’t performing properly. The sooner leaks in either are fixed, the better. Otherwise, more damage will be done.
To see if this is the case, try the following steps:
- Park your vehicle on level ground so nothing gets knocked over when opening the hood;
- Locate where everything connects at the underhood area – remove both caps from their reservoirs first then unscrew bolts holding them down (you may need a wrench for this);
- Check if the brake fluid level is below the minimum line and add more as needed;
- Replace components and tighten bolts securely. If all else fails, consult your mechanic about what could be causing this issue (and how best to fix it)

FAQs
How Often Should You Replace Brake Fluid?
In order to keep things operating properly, brake fluid must be updated on a regular basis (every two years or so). A brake system without enough protection against corrosion will eventually experience issues such as hard pedaling or locking up.
How Often Should You Replace Brake Pads?
Maintaining a smooth operation requires the replacement of brake pads every two years. Corrosion on metal surfaces in the brakes can lead to issues like hard pedals or locking up, if they aren’t addressed.
What Happens If You Don’t Change Your Brake Pads?
A buildup of corrosion on metal surfaces in the braking system can lead to issues such as hard pedals or a vehicle locking up if you don’t repair your brake pads periodically.
Replace them every two years so that they will live longer and perform better!
Also, don’t wait until there’s an issue, since it may be too late by that point.
Do I need Brake Pads To Drive?
It’s not necessary to drive, but you do need brake pads to stop. For example, an automobile without working brakes will not be able to come to a halt. When stopping at a high rate of speed, you may lose control and cause an accident or other harm (i. e. , hitting something).
Conclusion
If your brake pedal is firm or locks up, it’s time to get your car fixed up right away. Make careful to check the fluid before you buy pads or anything else. You can do it yourself by following these simple instructions if it needs to be changed.
If the problem persists, have your car inspected by a reputable mechanic for a brake inspection.
