What Does it Mean When Your Brakes "Lock Up"?
Brake "lock-up" can be most simply defined as any situation in which a vehicle's brakes are applied, but do not release as expected. This is a serious situation, in any event, but can be especially dire when it occurs while driving. In the most serious of cases, a wreck may take place as a result.
Contrary to popular belief, brake lock-up does not always mean that a vehicle's brakes have remained clamped to the point of causing full-wheel lock-up.
By definition, the term brake lock-up can be used to describe any situation in which a vehicle's brakes do not return to their "rest" position following a pedal application.
What Can Cause Brakes to Lock Up?
Though brake lock-up is nowhere near as prevalent as it was in the days prior to the use of modern ABS brakes, such issues do still occur on occasion. The vast majority of these issues are caused by substantially worn or otherwise compromised, brake system components.
The following are the most common causes of a vehicle's brakes locking up while driving.
- Use of improper brake fluid
- Overheated brake system components
- Damaged or exceedingly worn brake pads, calipers, and rotors
- Damaged or exceedingly worn brake drums, shoes, and wheel cylinders
- Seized/stuck brake caliper or wheel cylinder
What To Do When Your Brakes Lock Up While Driving
Experiencing brake lock-up while driving can be a harrowing ordeal. However, there are several key steps that should be followed to prevent a bad situation from becoming much worse. These steps are as follows.
#1 – Do Not Panic
The single most important thing to remember when experiencing brake lock-up is that it is imperative not to panic.
While this certainly sounds easier said than done, you also carry the responsibility of doing everything within your power to protect your passengers, as well as the other motorists around you.
Panicking robs you of your ability to think through the additional steps to follow.
#2 – Find a Place to Stop
The next item of consideration pertains to locating a safe place to come to a stop. Quickly scan your surroundings to determine what is at your disposal.
Parking lots, wide driveways, or even an empty shoulder make suitable locations for this purpose.
#3 – Carefully Exit the Roadway
Once you have determined the point at which you intend to stop, exit the roadway as carefully as possible. Though somewhat difficult to do at the moment, take into consideration all traffic that surrounds you.
If you must merge across lanes, signal if at all possible. Remember, poor decision-making at this point can lead to a much more dire situation.
#4 – Come to a Stop, Set E-Brake if Necessary
After pulling from the roadway, bring your vehicle to a stop as carefully as possible. If your vehicle appears to be pulling to one side or the other, setting your emergency brake can provide a certain level of stabilization.
However, it is important to remember that setting a vehicle's emergency brake at a high rate of speed can pose its own hazards.

#5 – Have the Vehicle Towed For Repair
After experiencing brake lock-up, a vehicle should not be driven under any circumstances, until proper repairs have been made. A vehicle should be towed to its intended point of repair, even if this location is only a short distance away.
How to Fix Locked Up Brakes
Following an incident of brake lock-up, it is imperative to determine the root cause of such a failure. Doing so often comes down to a matter of conducting a thorough visual inspection.
A vehicle's front and rear brakes should be inspected for signs of irregular wear, as well as component damage. Any deficiencies discovered during this inspection should be repaired prior to returning the affected vehicle to service.
In many cases, the offending brake assembly can be identified by a burnt smell, the presence of excess brake dust, or the blueing of the assembly's corresponding brake rotor or drum. If any signs of this nature are discovered, all brake components at that wheel end should be replaced.
Additionally, one might also wish to replace the same components at the opposite wheel end of the same given axle. At the very least, brake pads of a single axle should always be replaced in pairs.
In extreme cases, overheating as the result of brake lock-up can actually compromise the wheel bearing of the affected wheel end. When this occurs, subsequent replacement becomes necessary.
After all the repairs have been made, an initial brake test should be conducted in an isolated location, such as a parking lot or driveway, whenever possible.
If all appears to be in proper operating condition, a more thorough test drive can be conducted on a nearby roadway. If at any time, further additional issues become apparent, discontinue your test drive for further evaluation.
If for whatever reason, you are unsure about repairing your vehicle's brakes following an occurrence of lock-up, seek professional advice. There is no shame in seeking out a second opinion, or opting for professional repair.
After all, your life is quite literally riding on the functionality of your vehicle's brake system.
