Question about GMC Sonoma

1 Answer

I step on the brakes and the brake lights do not come on. Sometimes if I slam the pedal enough times they will start working, but now they will not come on at all. Do I need to replace the switch or is it something else?

Parking light wont go out and keeps dinging


Reach down and release the parking brake at the same time pull up on the parking brake pedal. Sometimes the pedal gets bumped just enough to engage the switch indicating the brake is engaged.

My brake pedal goes all the way to the floor


Brake pedal goes to the floor? When does it happen. That is the most important piece of information. Most brake systems are power assisted via vacuum from the engine. Your brake booster is what makes the "power assist" work. There are some specific times when you will feel your brake pedal "fade" to the floor and it is normal due to the cycle of the brake components operation.If your brake pedal goes to the floor every time you step on it, stop driving and get to a repair facility! If the pedal is working when driving and the vehicle seems to be working as it always has, then chances are there is no concern. To be on the safe side, have it checked the next time you are in for any other type of service.There is a sensor inside most brake reservoirs that activates the indicator light in your instrument cluster when the level is lower than it should be. As your brake pads wear down, the system requires more fluid so the level at the reservoir drops setting the light. Same thing if there is a leak. The fluid level drops and the light goes on. This brake fluid leak would most likely be combined with a spongy pedal or a pedal fade every time you step on the brakes. A leak would also almost always have a wet area around the leak. Sometimes the leak can be internal to a part of the car you cannot see, so don't count on it.One easy way to check most brake boosters and the brake system for leaks is to turn the vehicle off and pump the brake pedal. Every time you depress the pedal you should feel the pedal "height" come up and the pedal get harder. After a few firm pumps of the pedal, hold it down. Leave pressure on the pedal for 20 seconds or so. Does the pedal move slowly (or quickly) to the floor? If so then there is a leak somewhere in the system. Keeping pressure on the brake pedal, start the vehicle. Does the pedal no drop? It should. That is the power assisted vacuum kicking in as the engine starts to run.The bottom line is that we are talking about your brakes. Your life, your passengers lives and the lives of others on the road around you depends on that system working properly. If you have any doubts, or feel uncomfortable, take it in to have it looked at. Know specifically what it is doing so that you can have your repair facility look at what you are feeling and tell you if

Slam on brakes i feel a vibration in the pedal


This may be a silly response but are you sure it is not your ABS? This is the Anti-lock Braking System that prevents your tires from locking up when you slam on your brakes during an emergency. This helps prevent you from losing control of your vehicle. If any of your tires lock up your ABS will kick in and you will know this when your brake pedal starts to more or less vibrate. Sometimes when this happens your ABS light will come on your dash during the time your ABS is in use. This is a normal response and will happen more frequently when on icy, wet, or unpaved and muddy roads.

Brake lights stay on


The most probable cause is a sticking brake light switch. The brake light is activated by a small switch mounted under the driver's side, up near the leg of the brake pedal. That switch is spring backed so that when you depress the pedal the shaft of the switch is let forward and turns on the brake light. That switch sometimes comes loose or half cocked in the housing and stays activated all the time until you let the brake pedal loose and the leg of the pedal depresses the switch shaft just enough to turn off the brake light. The solution is to replace the switch, at about 15 bucks at your Advance Store. or 10 bucks plus shipping on the internet. You can check when you leave the vehicle to see if the brake lights are still on. Mind you, this does not happen all the time as sometimes it is cured by the action of the brake pedal knocking the shaft back in line

I have to boost vehicle off every morning.Battery and Alternator good but every morning battery dead after sitting over night.Hook battery cables up and starts up after a few minutes


I guess that your battery is being run down by a device sapping energy from the battery. I would guess off the top of my head that it is the brake lights as that is a common problem of vehicles. The brake light is activated by a small switch mounted under the driver's side, up near the leg of the brake pedal. That switch is spring backed so that when you depress the pedal the shaft of the switch is let forward and turns on the brake light. That switch sometimes comes loose or half cocked in the housing and stays activated all the time until you let the brake pedal loose and the leg of the pedal depresses the switch shaft just enough to turn off the brake light.

Brake lights not working change fuses,


There should be a switch under the brake pedal. This should opearate the brake lights. It is also not impossible for both the brakelight lightbulbs to blow at the same time.

Sometimes a trunklid slamming can break the filaments. Check the switch under the brake pedal first and remember to look at the backwindow light to see if it is working. The brake pedal switch is simple to install. The rear window light may work if the tailight wires are unplugged.

Renault clio abs light comes on with vibration through brake pedal. discs and pads renewed


How hard are you stepping on the brake pedal? What you are describing sounds like the ABS system activating. When you step on the pedal hard enough to engage the ABS the light will come on, in some cars it will blink. You will also feel the thumping/vibration in the pedal since the system works by repeatedly engaging and disengaging the brakes. If it is happening when you step lightly on the brakes then you may have a bad wheel speed sensor or possibly a bad or miss-adjusted brake switch.
