Q: Wondering how a brake pressure switch works? What makes the break light turn on?: Brake pressure switch? There is no such thing. Are you talking about the brake warning light in the dash and what would cause it to come on? A loss of brake function at the front or rear end of the vehicle could make the light come on. The light in the dash is hooked to a switch inside the proportioning valve (located under the hood). If you were losing brake fluid, say from a broken brake line, the proportioning valve would sense the loss of brake pressure on either end of the vehicle and the light would come on.

Q: I know it‘s meant to keep the car from skidding, and the idea is when wheels are sliding, they are undergoing kinetic friction, which is smaller than static friction, so it takes longer to slow the car down.If kinetic friction is really smaller than static friction, then why is it easier to move an object with wheels, versus and object that has no wheels?I‘m hearing that there is a third type of friction called rolling friction, which is even less than kinetic friction. If this is the case, then anti-lock braking systems are pointless, because you want to wheels to slide instead of roll.: I've had both. The anti-lock brakes definitely stop faster. Especially in snow, if you lock your brakes, you're sliding and barely stopping. Anti-lock brakes perform better. Kinetic friction between two materials is USUALLY smaller than static friction. Their are some rare material combinations where this is not the case. If kinetic friction is really smaller than static friction, then why is it easier to move an object with wheels, versus and object that has no wheels? The wheel has the least surface area making contact with the ground, meaning least impact of friction. You also have to consider that with anti-lock brakes, it's the pad touching the wheel that slows the car, vs. without anti-lock brakes, it's the wheel making contact with the road that is stopping the car. The friction experienced between these two is different, and with anti-lock brakes it's more friction.

Q: I recently replace my brakes. The front pads looked good. They looked to be about 25% worn. So I put them back on. The rear shoes were pretty worn down, almost to the metal, I would say about 95% worn. I bought the vehicle new, and the shoes and pads are the originals that came with the vehicle. Also, about a year ago, my ABS light came on and has been on ever since. My question is; what is causing the front to rear wear difference on the pads/shoes? Could this be something with the ABS system that is doing this?This is on a 1999 Isuzu Rodeo, with 112000 miles. Manual Shift, 2.2 L engine.: This is not normal, as the front pads generally wearout about 3 to 1 as compared to the back. Therefore if it has parking brake activated on rear axle, - I would assume they drove around a lot with parking brake on! Or possibly the shuttle valve) on brakes has shut off one circuit, - causing all the braking to be on rear wheels! This can happen if there was a leak in brakeline somewhere - this is supposed to prevent the 2 circuit brake system from failing completely,- so that you can't stop at all! (has been around since the 60s)! This should be obvious, if it is pretty hard to stop from road speed! However I would assume that the front pads had already been replaced a coulple times by the time you got the car! I get a bout 100K out of front pads in std. trans vehicle, --because I do most of the slowing down using friction and downshifting. Which means I do not arrive 50 feet from stopsign doing 40mph! I start shifting down 150 - 200 feet before stop, and am only going 10 mph or so which doesn't take much brake to stop all the way! The ABS light might just be telling you the the brake fluid is low, - or the the shuttle valve is stuck,- or that the system actually has other problems. Ther newer ones have electronic ABS systems, and can be a real nightmare to fix (moneywise),- when they get fouled up!

Q: Speak the working principle of the braking system: Automotive brake system is now generally divided into two kinds of hydraulic brake is another kind of pneumatic brake hydraulic brake is the brake master cylinder to brake fluid as the transmission medium through the brake pipe to each brake The pump to achieve the effect of brake and pneumatic brake is the high-pressure gas as the brake medium and then through the pipeline to the brake sub-pump to achieve the braking effect Need to point out that the hydraulic brake system brake points Pump and pneumatic brake system in the brake cylinder is not the same use is to note that the former is mainly applicable to small cars which are mainly applicable to large and medium-sized automotive engineering machinery.

Q: i know it somehow locks the back wheels, does it work like normal disc brakes? and ive heard some people use it for cornering, how so?: The normal brakes on a car are activated by a hydraulic system so that it just takes a little force on the pedal to apply a lot of braking force to all four wheels. The emergency brake doesn't use hydraulics - it just uses a cable going directly the the rear brakes. It won't stop you as fast but if you get air in your brake lines or something, it is better than nothing. Some people do use the emergency brake when drifting (cornering while sliding sideways) because it can help them initiate the slide. In a rear wheel drive car with a stick shift car, generally the driver will do a clutch kick and accelerate to get the rear wheels spinning. If that alone doesn't do it, he can pull the handbrake to lock the rear wheels before dropping the clutch and accelerating to spin them. In a front wheel drive car, you can't make the rear wheels spin so locking them up is the only way to reduce traction on command. Pulling the handbrake accomplishes this. Drifting is dangerous, hard on the car and very hard on the tires. I wouldn't suggest trying it.

Q: i want to add an disc brake system to my car: It would cost you more than the car.

Q: I dont think it is the brakes or rotors causing the problem after reading up. Its like u almost gotta pump or slam the brakes to get it to stop and its really weak. The brake pedal feels different when pushing it in too. What do you think it is? This is a 94 4x4 explorer, what do you think this would cost also?: If the problem has occurred without having performed any recent work, then replace the master cylinder. If you have recently replaced callipers or wheel cylinder, then bleed the brakes. Gravity bleeding is the easiest to do by yourself. 1. Fill Master Cylinder 2. Loosen the RR bleeder [may have to push the brake pedal to begin the process] 3. Allow to drip until no bubbles are visible 4. Move to RR FR FL 5. Constantly monitor the master cylinder level 6. Clean off brake fluid with brake cleaner or Methyl Hydrate Should cost no more than a $100

Q: I noticed that the brake fluid reservoirs are located high enough to be above the brake levers. why is this? Does it have something to do with gravity pushing the brake fluid down so the system is filled with brake fluid at all times?: This Site Might Help You. RE: why are brake fluid reservoirs located so high on motorcycles? I noticed that the brake fluid reservoirs are located high enough to be above the brake levers. why is this? Does it have something to do with gravity pushing the brake fluid down so the system is filled with brake fluid at all times?

Q: I have a 2005 Dodge Ram 1500 quad cab pickup. I went camping over the weekend and while driving home the ABS/Brake warning light came on. I knew that my brake fluid was a little low so I stopped filled it and continued to drive. The warning lights continued to stay on and I noticed that the actual tail lights stayed on the whole time.( My brake lights didn‘t work). Even with the car off. I had to disconnect the battery. Any Ideas what could be causing this?: This was tremendously helpful as serving to to diagnose the concern! Our 2007 Camry began to have problems after a brake job within the back. It has been intermittently going wacky. Sometimes it labored most occasions now not. It was advocated by means of the vendor to interchange the $5000 ABS brake actuator process. I began with exchanging the ABS/tempurture manage pc that is under the passenger dash and it had no result. I made up our minds to get some electrical contact cleaner thinking that perhaps the connector was once soiled causing the partial connection. However, once I was once down looking at the connections and sensors I discovered the left driver aspect connector was once no longer thoroughly seated. It gave the look to be set but when you pulled, the connector would come off. Sincerely the rubber throughout the connector got squished to the again of the connector, causing the connector to no longer entirely click into position. Correcting the connector in order that it clicked into position entirely solved the drawback! Simple as that however hard to search out. I inspiration it perhaps an easier situation to begin diagnosing. Hope it helps. Thanks once more, Caleb Kelsay

Q: 2002 F-250 5.4L 4x4Changed ball-joints and hub assemblys. lol. Can do all that but can‘t get brakes lol.Well I got new pads and rotors. Had one hell of a time getting the pads in using old anti-rattle clips. But once I grinded them and the spot underneath them with a buffer (wire) brush they went in better. Everything is fine. But when I put the caliper on (the pistons are in all the way) the rotor will not turn at all. I didn‘t change the pins or boots on caliper because they are jammed in there. My guess is that has a big part in it. Only other thing I can think of other than heating them up to take them out and put new pins and boots in; is new clips. Any other suggestions?: The pistons must be pushed open. Do not use a torch on the brakes. Do not grind them down. Look in Chilton's Auto Repair manual to see how to do the job right. Different cars have different methods.
