E-brake adjust.
My pickup rolls on an incline even with e-brake on. The brake pedal reaches floor board when fully depressed.
My car has 205000 miles.
My car has a manual transmission.
Experienced mechanics share their insights in answering this question :
Hello. These are two separate issues as the brake pedal is a hydraulic system operating with brake pads and rotors and the e-brake is a brake cable that leads to a brake drum assembly.
First, lets address the brake pedal as that is a much more crucial part to everyday driving. The brake pedal going to the floor could mean a few different things. Here is what I would recommend:
Check the brake fluid to be sure there is enough fluid.
Check the pad thickness. If they are completely worn down this could cause the pedal to go very far down to the floor.
Check the brake booster to be sure it does not have a vacuum leak. For the vacuum leak test, let the truck idle without touching the brake pedal for at least a minute. Turn the engine off and wait one minute. Test for the presence of vacuum assist by pressing the brake pedal and releasing it several times. If there is vacuum present in the system, less and less pedal travel will occur.
As for the e-brake. Start by checking to see if the cable is broken by tracing it underneath the truck along the frame to the rear of the truck to the brake drum. Check to be sure the spring is still intact. If everything appears normal, pull the brake drum hub off to inspect it. Sometimes the brake shoes are too worn to grab when the e-brake is applied.
If you need assistance having this problem taken care of, a certified professional from YourMechanic can come to your home or office to diagnose the brake system for you.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
Pull the handbrake lever `on` until slight resistance is felt at the lever; then try turning each rear wheel. Each should turn with equal resistance. If they do not, tighten the cable on the slacker side until both feel equal. Tighten the locknuts.
Adjusting Parking Brake
It`s recommended to change your e-brake at 75,000 miles or at least adjust it every 2 years, depending on how often you use it. If you`re e-brake feels loose, it`s usually the wires that simply need to be re-adjusted.
Remove the rubber boot around the handbrake. You will now see two nuts in front of the lever. These nuts are used to adjust the parking brake. Slowly pull up on the handbrake until it clicks five times.
Bad Switch: One common reason for the Parking Brake light to stay on is a failing or failed switch. This can be checked easily by jiggling the handle after it is down. If the light turns off (or turns off and then back on), the switch is the most likely culprit and will need to be replaced.
Parking brake shoes are designed to self-adjust, but the self-adjusting system can often fail. The brake shoe is housed in the drum and experiences lots of heat and brake dust that eventually leads to wear and tear.
Pedal – The pedal emergency brake is a small pedal that is positioned on the floor and to the left of the gas, brake and clutch pedals. Press down on the pedal until you hear it click to engage it. Pull the lever above the foot pedal to release the brake.
So, what makes an emergency brake different? It`s all in the name. Some automakers call it a parking brake, while some call it an emergency brake. While calling the auxiliary brake system a parking brake implies you use it every time you park your car, the name emergency brake implies it`s only for emergencies.
Rotate the brake disc and look through the adjustment slot to check each brake shoe in turn. If there is enough lining left, use a screwdriver to turn the star wheel adjuster until the wheel is locked. Back off the adjuster half a turn.
In an emergency, the parking brake can be activated when the vehicle is moving by pressing and holding in the button. The brakes will then be applied with force in order to brake the vehicle. The braking process is canceled when the button is released or if the accelerator pedal is depressed.
Faulty Switch: One common reason for the Parking Brake light to stay on is a failing or failed switch. This can be checked easily by moving the handle to and fro after it is down. If the light turns off (or turns off and then back on), the switch is the most likely culprit and will need to be replaced.
If the parking brake cable becomes excessively worn or stretched, it will not be able to pull the parking brake as tightly. This will result in the parking brake not being able to hold the weight of the vehicle, which may cause it to roll or lean, even when the parking brake is fully engaged.
Need to Adjust Brake Shoes: The single most common reason your parking brake won`t engage is a need to adjust the brake shoes. This requires removing the rear wheels, removing the drum, and then adjusting the wheel to spread the shoes apart. Both sides should be adjusted.
A good way to tell if your e-brake is failing is to observe your truck on non-level ground after applying the e-brake. If your truck moves, then the e-brake is likely bad. Another clear sign that the e-brake is bad is if the emergency brake light in the dash comes on. (Only on some vehicles.)
If you have an older car, you will probably have a lever in the middle console. To engage the brake, you will pull up on the lever located between the driver`s seat and the front passenger`s seat. To disengage the parking brake, push the button at the end of the lever and push it back down.
Full engagement should take place near or less than ½ the parking brake`s travel. If the parking brake travels more than half the distance, it could be too loose. If the parking brake fully engages in less than ¼ travel it could be too tight.
This is due to the poor condition of the battery. It is therefore important to check and ensure that all electronic devices in the vehicle are in perfect working order.
If the weather is cold and wet, it is very likely that your e-brake has simply frozen in place. This can be resolved by turning on your vehicle and letting it warm up. Another reason your emergency brake gets stuck is pulling it too hard. Don`t treat your e-brake lever like a strength test from a carnival game.

Engine shaking while in neutral and park
ANSWER : It’s possible you may have disturbed a vacuum hose while you were doing the job, check for that first. But I’m concerned about the valves because If you get the valve clearance too tight, it may develop a miss at idle. This is because the affected cylinder cannot get enough compression to fire at low engine speeds. I recommend you re-visit the valve adjustment right away, because driving with a valve adjusted too tight can quickly lead to a burnt valve. If you don’t find a problem in the valve adjustment, then it’s time to look at other possible causes. If you’d like to have another pair of eyes look at this to be sure, contact Your Mechanic to have a technician come to your home or office to check your valve adjustment and your misfire for you.
cannot move the steering wheel adjustment lever up or down to adjust hight
ANSWER : Hello.
If the steering adjustment lever appears to be stuck then it may be possible that there is an issue with the mechanism. If the lever is manual type, then it uses pressure and friction to keep the wheel in position, and it may be possible that it is damaged or stuck. As most steering wheel adjustment mechanisms use pressure to hold the wheel, if it is stuck, it may simply require a bit of force to loosen. If the adjustment mechanism is electric, it may be possible that the actual adjuster switch has failed, or that the motor / actuator that operates the steering adjustment has gone bad. I would try to determine if the adjustment mechanism is electric or manual, and go from there, as the causes will differ depending on the type of mechanism. If you need assistance with this, a certified YourMechanic technician can be dispatched to your location to help inspect your steering wheel issue, to diagnose and repair this for you.

I have a dodge ram 2010 quad cap I noticed the other day after my wife reset the driver set when I tried to adjust the power seat
ANSWER : Hi there. The screw or cap could have been underneath the seat from anything, but if the seat was not adjusting then the screw or cap could have gotten into the track and jammed up the seat motor. Look around the seat tracks and see if anything is missing a cap or screw. Make sure that there is nothing in the tracks to allow the seat to move normally. If you need further assistance with your power seats, then seek out a professional, such as one from Your Mechanic, to help you.
