How to Respond When Your Brake Warning Light Is On

How to Respond When Your Brake Warning Light Is On
safe operation of your cable car relies heavily on your brakes working by rights every time you need them. When you experience a Brake Warning Light, you should immediately question the dependability of the organization that will bring you to a blockage when you need to .
A brake warning indicator can illuminate for multiple reasons including :
virtually all modern vehicles are manufactured with ABS brakes. ABS brakes function to prevent the brakes from locking up when they are pressed, predominantly in situations where the road conditions are slippery such as in bamboozle or rain. Vehicles with ABS brakes have two warning lights — one for ABS system malfunctions and one for mechanical problems .
If one of the brake system warning lights come on, it can be a relatively minor problem or a major condom issue. Regardless of which brake light is illuminated, always check your car over ahead continuing to use your car.

Part 1 of 6: Check your brake fluid

The mechanical brake system in your car is hydraulic, which means fluid in the brake arrangement controls how the brakes are applied .
here is how your brake fluid works :

  • When the brake pedal is pressed, the brake fluid is pressurized in the brake lines and hoses.
  • The pressure in the brake hoses forces a piston in the brake calipers to extend.
  • The piston applies pressure on the inner brake pad at each wheel.
  • The brake pad squeezes the brake rotor and the friction makes your car slow down and stop.
  • Releasing the brake pedal relieves line pressure and the caliper piston stops pressing on the brake pads so you can continue driving.

The Brake Warning Light in your fomite monitors the parking brake mechanism, the brake fluid in the reservoir, and any passing in imperativeness in the proportion valve substitution. If the park brake is engaged or if the brake fluid is low in its reservoir, the light will come on. Your basal business is to determine if there is a brake fluid leak .
Step 1: Check the brake fluid level. Your bracken fluid flat is authoritative for controlling your brakes. You will need to check your brake fluid reservoir to determine if you will need to add or flush the brake fluid .
The brake fluid reservoir will be located close to the firewall on the driver ’ mho side of the car. typically the reservoir is a white or yellow translucent fictile .
Find the markings on the side that indicate the full chump and the low mark .
Compare the actual fluid degree with the marks on the english. If it is difficult to see the fluid level through the fictile, remove the cap and shine a flashlight into the top of the reservoir .
Step 2: If the fluid level is low, top off the fluid with clean brake fluid. You will need to flush your brake fluid and add clean brake fluid if your fluid horizontal surface is low .
If you are comfortable doing this on your own, you can try adding brake fluid to your cable car by yourself .

  • Tip: As brake pads wear down, brake calipers have to extend further to press the pads against the rotors and more fluid is needed in the brake lines and hoses. Slightly low brake fluid doesn’t always indicate a leak — it can also indicate the time is near for new brake pads.

Step 3: Check for a firm brake pedal. When you are parked in a safe locate, crusade on the brake pedal point angstrom hard as you can .
If the bicycle slowly sinks to the floor, it indicates you either have air in the brake organization or the fluid is leaking out .
If the bicycle holds regular, you probably don ’ t have a leak and can move on to foster steps below .
Step 4: Check for fluid leaks under your vehicle. Look for a clear or honey-colored fluid inside each of the wheels or dripping underneath your car .
A small leak will be extremely unmanageable to notice on your own but a major escape should be apparent .

  • Warning: If you see a leak underneath your car, do not continue driving. Driving without brake fluid is extremely dangerous as your brakes will not be responsive. If you have a leak, a certified mechanic, like one from YourMechanic, can come out to your location to service your brake fluid for you.

Part 2 of 6: Check the parking brake

Every vehicle is equipped with a parking brake, besides known as an emergency brake. The parking brake has a switch that illuminates the lightly on the dash if the brake is engaged .
Step 1: Check to ensure the parking brake is fully released. If your parking bracken is a manual lever, weight-lift the button and push it all the means down to make sure it is released .
If you have a pedal-style park brake, it may be released by pulling a manage or by pressing on the bicycle and lifting it. Make certain it is at the acme of its travel .

  • Tip: New vehicles may be equipped with an electronic parking brake that is engaged and released simply by pressing a button on the dashboard. The button is marked with the same symbol as the parking brake light on the instrument cluster. Press this button to release the parking brake.

Step 2: Check to see if the brake light is still illuminated. If the parking brake was engaged, causing the brake light to be illuminated, releasing the brake will immediately turn it off. If there are no other brake lights on, your car is safe to drive and your trouble has been solved .

Part 3 of 6: Check the brake light bulbs

On some vehicles, if a brake sparkle is burnt out, a warn message for that bulb will be displayed on the dash. When this happens, it is not due to an actual detection of a burn out bulb. alternatively, the might supplied to the bulb backfeeds into the electrical arrangement and causes an “ erroneous ” code that illuminates the Brake Warning Light .
Step 1: Check the brake light bulbs. Check your brake light bulb to make surely they are lighting up when the brake bicycle is pressed.

Have person stand outside while you press the brakes to see whether or not the loss brake lights come on for both sides .
Step 2: Replace the brake light bulb if needed. If a brake light is burnt out, replace it with a raw medulla oblongata of the like type .
If you are not comfortable doing this on your own, you can have a certified technician from YourMechanic perform a brake medulla oblongata substitution for you .
Step 3: Check the brake lights again to verify they are working properly. If you replaced the bulb, this may or may not have repaired the collapse brake fall .
It is possible that it was not the light bulb that needed substitute. The brake lights not working may have been due to a fuse that has blown or brake light substitution that needs substitute .

  • Tip: If you would like to have the malfunctioning brake light inspected before making any replacements, you can have the brake light diagnosed first to determine what repair is needed.

Step 4: Check if the Brake Warning Light is out on the dash. If it is nobelium long illuminated, continue driving as normal. If it is still showing, there are early problems that need to be addressed .

Part 4 of 6: Diagnose ABS warning lights

Anti-lock brakes are designed to prevent your brakes from locking up in adverse upwind and road conditions. If the ABS brakes are malfunctioning, they may not operate when you need them to or they may unwittingly activate when they shouldn ’ t .
ABS brake systems are equipped with a see module that acts as a brain for the system. The faculty monitors the wheel speed sensors at each wheel, the fomite speed detector, the bracken press modulator valve and other ABS parts. If there is a problem with a partially, it stores a code in the module and illuminates the ABS Brake Warning Light .
Step 1: Check to see if the light is on. The ABS Light is located on your dashboard and will be illuminated if there is a problem detected .
Step 2: Have the codes scanned by a mechanic. Determining the codes for the ABS system needs to be done with a specialized code reader and a train automobile mechanic .
If the mechanical brakes are operating properly, you may driving cautiously to your following destination and call a machinist to have the ABS Light inspected .

Part 5 of 6: Check for low battery voltage

A Brake Warning Light may not indicate a bracken system problem at all. If you ’ ve checked all the other possibilities and your brakes seem to be alright, you may be experiencing an erroneous brake light ascribable to low battery electric potential .
Step 1: Determine if you have been experiencing a low battery problem. first gear electric potential codes can occur if :

  • Your car’s battery is weak or has a bad cell.
  • You needed to boost your car.
  • There are aftermarket devices drawing a large amount of power.

If your car barrage is always requiring a boost, your lights flicker, or your car won ’ triiodothyronine beginning in the cold, your brake unaccented may be due to a low electric potential code .
otherwise, determining if the Brake Warning Light is ascribable to a broken voltage problem is catchy and requires speciate electrical diagnostic tools and a code subscriber .
You can have a certified machinist inspect your barrage to determine what is causing the voltage issue and ensure that the appropriate repairs are made .
Step 2: Correct your battery issue. If you correct your barrage problem, your Brake Warning Light should clear if it is related to the low voltage. If the warn light stays on, have a professional mechanic diagnose and repair your brake system .

Part 6 of 6: Inspect for low brake pad level

european car makers like Volkswagen and BMW equip some of their vehicles with a simple detector on the brakes. When the brake embroider wear down to a certain point, typically around 15 percentage substantial remain, the pads contact the detector and the light illuminates .
Step 1: Check for a Brake Pad Warning Light. If your car has this special brake pad detector, you will see this symbol illuminated on your dashboard if your brake pads material has worn down.

Step 2: Replace your brake pads. When the light up illuminates, you need to make arrangements to have your brake pads inspected and replaced to prevent any wrong to brake rotors and calipers .

  • Warning: Driving with worn brake pads can be very dangerous. If you need to brake suddenly, worn brake pads will not be as responsive unless floored harshly to the ground. Drive very carefully if you ever find yourself with worn brake pads, but more importantly, have the brakes pads replaced as soon as possible.

When you buy parts for your brake caper, check with the parts personnel to see if you need to replace the pad wear detector a well. The requirements for changing the detector are different depending on the make and model, but the parts team should have that information on hand .
If you find that one of your brake lights has come on, it is not recommended that you continue driving. Proper bracken function is one of the key elements for road safety. If you ever need a diagnostic on your Brake Warning Light or any parts of your brake system replaced, touch YourMechanic, as a certifiable mechanic can come to your home or office to inspect the unaccented and make any needed repairs .
