Situations such as heavy loads or long downhill grades where the brakes are used heavily can lead to overheating of the lining, drums, or brake fluid, resulting in a loss of braking called: Which brake is used for holding a vehicle in place when its stationary? c. Both A and B "Scratcher" and "sensor" are types of disc brake pad __________ indicators. There is also typically a separate, mechanical parking/emergency brake, either cable or electrically operated, that works only on the rear wheels. Additionally, brake dragging can also be caused by frozen emergency brake cables as well as . a. VAV_\text{A}VA and I1I_1I1? If your brakes squeak and you want to know why, maybe I can help! Another uncommon cause of a soft pedal and long travel, is a bad wheel bearing, which is unrelated to the brakes except for being in the vicinity of the rotors. If this is what is going on, you need to identify and replace the faulty part. One safe way to test whether a braking problem is at the front or rear brakes is to drive at a low speed and: (7.1.2) * low brake fluid All of the following can cause brake pedal pulsation, EXCEPT internal master cylinder leak All of the following can cause brake system dragging, EXCEPT fixed and sliding Disc Brake System Flashcards | Quizlet Question: My Chevrolet 2006 has some braking problems. Technician A says to verify the wheel speed sensor operation and compare all four wheel speed sensor outputs to the data list. Consider a system consisting of both objects A and B. Correct answer D-Both technicians are wrong because this is how power brakes are supposed to operate. Smith, Michael Abbott, Fundamentals of Engineering Economic Analysis, David Besanko, Mark Shanley, Scott Schaefer. b. First, it can act like a restrictor in the line. Brake dragging is commonly caused by broken or weak springs on the drum brakes. The braking systems commonly found on modern vehicles are composed of several components that work together to slow and stop the vehicle. Which is the correct way to service these brakes? Correct answer B-Insufficient clearance between the pads and caliper slider causes the slider not to move and only applies one brake pad causing only that pad to wear. When you are in a crisis situation like a brake problem, some mechanics will take advantage of the customer and over-sell the work that really needs to be done. Technician A says excessive rotor run out could be the cause. To further reduce the noise, do not machine the rotor more than needed. Even today, your brakes can fail completely, but there are failsafes built into the system to prevent that from happening in most cases. A common symptom of this type of braking issue is a burning smell from the amount of heat the hung up brake generates. D. Neither technician. b. Arcing Here are five of the most common brake problems I run into, starting with the most serious. Why is there a rear knocking noise from the drums when applying the brakes? B only If you try to fix it by adjusting the rear drum brakes, you will still have the problem until you fix the adjusters. B. Correct answer A-Excessive tire pressure is the exception because this fault will cause tire wear but not a pull. One of the first symptoms of bad or failing drum brakes is unusual brake pedal feel. Technician A is wrong because the proportioning valve only affects brake lockup and is not used on 4-wheel disc brakes only on disc/drum combinations. d. while driving the vehicle slowly. To do this test, drive your car in a remote location with no traffic at a speed of about 30 miles an hour. Brakes, when applied must not disrupt steering geometry. a. The suspension additionally steering service area involves the following components: Steering system, Suspension system, Wheel Alignment and Wheel and Tires Service Log. Your brakes pull to the good side. In the brake booster there is a washer that is suppose to keep the pushrod centered as it goes into the mastercylinder. The sliding and moving parts of the brake system require lubrication to prevent them from binding. Technician A says excessive brake pedal freeplay could be the cause. Dragging brakes must be repaired because it results in overheated parts and possible damage to the brake system. The failing bearing allows the hub to move around, effectively pushing the brake pads back into the caliper as far as it can. Who is correct? If your car sits for long periods without moving, moisture from rain or high humidity causes your rotors to rust, except for the patch of rotor surface where the pads rest.
