    Digital Electronic Trailer Brake Controller? Electronic brake controller for a trailer

    View Comment
    1. Reply

      Go to the dealership where you bought your pick-up, and make sure your pick-up has the towing package so you can pull your trailer. If your pick-up doesn’t already have the towing package, you can ruin your transmission by pulling your trailer, especially if your trailer is loaded. They will also install the electronic trailer brake controller. Once it’s installed, there will be a switch under the steering wheel column. When your trailer is loaded, use your trailer brake instead of your pedal brake. This will slow your trailer down so that your trailer won’t jack-knife. Using the trailer brake also helps your pick-up brakes from wearing out so soon.

    Why Does Brake Petal Squeeks? When my brakes are used a while the brake petal squeaks what can I do

      Could be that your brake pads are worn down to the point where they need to be replaced.

      Most cars have brake pad warning indicators that squeal when the brakes are applies and the pads are worn to the point that they need to be replaced.

      It could also be that you’ve had brake work done recently and the brake hardware did not get the high temperature grease applied that stops brake noises.

      Another possibility is that the pads have built up some brake dust and that can cause squealing.

      The brake dust problem is easily corrected by blowing the brake assemblies with compressed air to get rid of the dust build up.

      Disc Brake Basics
      Here is the location of the disc brakes in a car:

      Disc brake location

      The main components of a disc brake are:

      oThe brake pads
      oThe caliper, which contains a piston
      oThe rotor, which is mounted to the hub

      Parts of a disc brake

      The disc brake is a lot like the brakes on a bicycle. Bicycle brakes have a caliper, which squeezes the brake pads against the wheel. In a disc brake, the brake pads squeeze the rotor instead of the wheel, and the force is transmitted hydraulically instead of through a cable. Friction between the pads and the disc slows the disc down.

      A moving car has a certain amount of kinetic energy, and the brakes have to remove this energy from the car in order to stop it. How do the brakes do this? Each time you stop your car, your brakes convert the kinetic energy to heat generated by the friction between the pads and the disc. Most car disc brakes are vented.

      Disc brake vents

      Vented disc brakes have a set of vanes, between the two sides of the disc, that pumps air through the disc to provide cooling.

      water gets on pads and disc

      what to dry

    Changed My Brake Pads? I changed my brake pads yesterday. The brakes work perfectly and the brake fluid is at the proper level, but my brake light came on this morning. What could that be?

      Changing pads is a simple thing usually.

      Now, the light. When you said the brake light, there are two lights that you could be referrring to.

      1. The red brake lights at the rear of your vehicle.
      If this light is coming on and STAYING on, there is a problem with your Brake Light Switch or Stop Light Switch. Only difference between the two is the name (as in, which part of the world/country you live in). The brake light switch is located at the bottom of your brake pedal. When the button is pressed, it turns the brake lights off (your pedal pushes it in when it’s ‘at rest’). When you press on your brake pedal, the button is released and you complete the electrical circuit (think of flipping a light switch in the house) and the brake lights light up as they should.

      2. Your ABS light on your dash.
      If you have an Anti-Lock Braking System, when there is an issue with THAT system, your ABS light will come on and stay on. An issue could be a simple malfunction/defect in the electronics of the system OR it could be the brake pads themselves. If you installed pads that were not designed for an ABS system…. that would be an issue.

      #1 can be simple enough that you can do it yourself

      #2 is an issue that I would take to a mechanic that specializes in Brakes.

      If you had a professional (licensed shop) mechanic do the work for you, LET THEM KNOW what issue just happened. MOST mechanics pride themselves in their work, especially if they value their reputation, and want you to have a vehicle that is in proper working order that has their name on it for repairs.

      If you did the work yourself or a ‘shade tree’ mechanic (and not all are bad, some DO know what they are doing) was the one who did the work for you, let them know as well. If they say ‘i don’t know’ or start to scratch their head, seek out a professional shop and be prepared to pay the money that you should have paid to begin with.
      If you can recoup any of your costs from the ‘shade tree’, congratulations.

    What Is Regenerative Braking? What is Regenerative braking and how does it help

    View Comment
    1. Reply

      Regenerative braking is used in hybrid vehicles. The energy from braking that is normally just creates heat is instead used to help charge up the hybrid batteries.

      In the case of a hybrid, instead of just applying the brakes that rely on friction from the brake pads and/or shoes to slow down the vehicle, a hybrid’s brakes may also use the electrical motor to slow the vehicle. When the motor is spun backwards (which is what happens when it is used for braking), the motor becomes a generator and the power it creates is sent to battery for later use when accelerating.
      This usually only happens when the vehicle is braking from slower speeds. Hybrid vehicles also have conventional brakes and they are used at higher speeds, such as on the highway.

    Car Brakes Making High Pitched Noise? I got a 2010 toyota rav4. 9000 miles. ABS brakes
    Recently, when i start braking, the brakes start making a high pitched noise, then when i push the brake pedal deeper, it stops… is this normal?? HELP!
    im 16 too =P
    Alright, im going to toyota today =)

      Brakes are metallic, rotors are metal. two metal surfaces running against each other will cause friction & sometimes ‘polish’ the surfaces of the brakes and rotors, causing a squealing sound.

      or your brakes are vibrating & causing a pitch from high frequency virbrations. either way it shoul dbe under warranty so just bring it into the dealer

      the metal wear strip will sound more screeching like nails on a chalkboard and the sound won’t go away if you press harder on the brakes

    2000 Bmw 323i Brake Light On? My brake light came on I think its the brake sensor. I just looked at the brakes and took them apart and and found out the rear brakes are worn down to the sensor and the light wont go out,.I replaced the rear breaks and sensor and the light is still on.Whats the problem

      Usually when your brake light comes on the dashboard, It means that either you got the parking brake engaged or the pressure in the master cylinder (brake cylinder) is low when you press the brake petal.
      There is no sensor on the rear brakes pads and the only “sensor” on the rear brakes is for ABS (if your car uses a sensor for ABS activation on the rear brakes)

      Look around for leaking brake fluid or see if your parking brake cable is frozen.

    Air Brakes Vs. Pneumatic/hydraulic? What are the advantages of air brakes over pneumatic/hydraulic brakes when considering purchase of a bus or RV?

    View Comment
    1. Reply

      With hydraulic brakes the wheel cylinders (drum brakes) or calipers (disc brakes) are right at the wheels and absorb heat from the braking action. When brakes get hot the hydraulic fluid can boil. When it boils it becomes a vapor, which is not compressible and you wind up with no brakes. Heavy vehicles like buses and RVs take longer to stop hence more brake use and more heat build up. I have seen a lot of RVs with hydraulic brakes experience brake failure in mountain driving where a lot of braking is required. With air brakes the brakes are operated by air cylinders moving mechanical linkage to apply the brakes. their isn’t any fluid to heat. You can still lose the brakes by over use and burning the linings but that is a rare occurrence.

    Are These Bike Brakes Good? Are tektro novela disc brakes good?

    View Comment

      Can’t find pads for them. So good luck once the pads wear out.

      If they were Avid or Shimano this wouldn’t be a question. I particularly like the Avid BB7 mechanical disc brake. Avid includes superb support and the product works very well with standard v brake levers.

      If the bike you are looking at had V brakes, this wouldn’t even be a discussion. Tektro makes decent V brakes and parts are readily available.

    Question About The Cars Braking System? On a car are the front brakes the main brakes then the rear are applied to help or are the back the main then the front applied to help? any help is apprciated

    View Comment

      Both front and rear brakes work in unison to slow or stop the car. You’ll notice if your car has rear wheel disc brakes, the diameter of the rotors, brake calipers and pads are smaller. In the braking system is a brake proportioning valve which controls brake pressure to the rear calipers or brake shoes. Rear brake pressure is always less than the front even though the shoes and pads contact their friction surfaces at the same time. Front wheel driven cars 805 of all braking is done automatically by the front wheels. Rear wheel drive cars 70% of all braking is done by the front wheels.

      If the rear brakes came on before the front the car would spin-out in rain or snow covered roads. If the rear wheel braking percentage was too high the car would swap ends!
