Brakes and Tires

Vehicles require brakes and tires to be steered and controlled. Tires allow better vehicle performance by providing a flexible cushion to absorb the shock, while brakes control the spin of the tires, thus controlling the speed of the vehicle.

Do you turn brake rotors every time you replace pads?

Not if no shake or bounce upon braking, grooves in rotor shorten pad life,if braking is smooth just pads wore out, put a fresh set on don`t look back Not if no shake or bounce upon braking, grooves in rotor shorten pad life,if braking is smooth just pads wore out, put a fresh set on don`t look back Not if no shake or bounce upon braking, grooves in rotor shorten pad life,if braking is smooth just pads wore out, put a fresh set on don`t look back

What are disc brakes made of?

Depending on the car, some disc brakes are made of steel, aluminum or carbon fiber.

How long do tires last?

There's no way to answer this question; there are way too many variables. A harder-compound cruiser tire could last as long as 20K-25K, while a soft compound sportbike tire could last as little as 2000 miles. The type of tire, the compound out of which it is manufactured, the power of the motorcycle on which it is mounted, and the way the rider rides all figure into this equation, as well as many other factors.

How can you tell if master cylinder is worn out?

Start the car, place you foot on the brake and push and hold it. If the brake pedal very slowly sinks toward the floor, the master cylinder is bad. Of course a leak at the master cylinder means it is bad. Don't ignore any of these 2 symptoms as it can stop working at any moment, and leave you with no brakes. When looking at the master cylinder look at the wall or booster that the master is bolted to. If u see sweating, or paint pielling at the mating the master is leaking from the seals.

Can you replace a R255 tire with a R265?

NO, you would want to go with a 225/70-17 to equal a 235/65-17 A 265/70-17 is equal to a 275/65-17 and are way too big for this car. My advice is stick with the exact same size tires that came on the car.

Where do you find the expiration date on a tire?

There is no date. Expiration depends on wear. However, you may find the production date on a tire. Look for the DOT numbers on what would be the inside of the tire. Example, DOT 02112 would be the 21st week of 2012 that tire was produced.

Why is your abs brake light and park brake on in your 2002 Dodge Dakota?

The ABS (antilock brake system) light is on because there is a problem with the ABS system. Until that problem is fixed, the light will remain on and the ABS system will not be functioning. You will still have regular brakes but without the ABS function. Take it to a qualified mechanic for repair.

What size tire can you put on a xj stock 15inch rim?

First,consider the dimensions of the wheelwell,plus the 'offset' and diameter of the rims which are to be installed. This determines which size tires are feasible to mount to the rims. 'Plus-sizing' can be tricky,so do some research before busting your butt finding out what works. Sorry I couldn't be a little more specific,it just kinda depends on what can fit. Lift kits increase the size 'big time',but you mentioned that the vehicle is stock. Inquire at tire service or speed shops as well. Good Luck!

How do you know when your brakes are bad?

Several things to watch for. Your brakes will sometimes start to stutter or pulse as you apply them. Occasionally you will hear a noise like a grinding or a squeal. With any luck, it'll be the pads wearing out before the rotors get damaged, but that''s not the way things usually happen. People have a tendency to let things go until more work is involved. If addressed soon enough, most rotors can be turned and used again, If left too long without attention, you will need to replace the pads, the rotors, and sometimes even the calipers, so...best to take care of things as soon as you can.

What do the tire numbers mean?

In a tire with metric sizing, on an example of 120/70ZR17:

120=tire width in millimeters

70=aspect ratio

Z=speed rating

R=construction type

17=rim diameter in inches

In a tire with alpha numeric sizing, on an example of MT90H16:

M=motorcycle use

T=tire width code

90=aspect ratio

H=speed rating

16=rim diameter

How does a car disc brake work?

A disc brake is the most common front car brake, and is now often seen on the back too. The system consists of a rotor, a thick, smooth steel disc fixed to the hub and rotating with the wheel. At one side of this rotor is a caliper fitting around part of it and fixed to the knuckle (hub mounting). This caliper contains a hydraulic piston (often two) and two disc pads. These are steel pads faced with about 3/8 inch of friction material. these friction material sides rub on the rotor. When hydraulic pressure is applied via the brake pedal, this forces brake fluid to move the piston out, squeezing the pads, causing them to grip the rotor which then slows down or stops. This is obviously a very simplified description. -Modern systems have all kinds of improvements and innovations.

Why the abs light comes on in your chrysler 300 1999?

The ABS light is on because the ABS module detects something is wrong with the system. It will remain on until it is fixed. As long as the light is on the ABS system will not function if needed. Take it to a trusted garage for diagnoses.

Why does my brake pads sound like they're rubbing or grinding even after the brake pads were replaced the rotors were turned and they were greased?

Some cheap pads will squeal. You may need to change to an OEM type pad. It can also be you did not apply a anti-squeal high temperature grease to the back of the pads where they contact the caliber. Teflon coated shims are another option. Be sure and also check the slide pins to make sure they are not rusted. Apply a slight amount of high temp grease to these pins or replace if they are rusted.

What are best tires for your car?

There are many good quality tire manufacturers. More importantly, though, you should always stick with the tires specified by the vehicle's manufacturer. You can find the information on tire size and type on a decal on either the driver's or the passenger's door jamb.

How do you fix a brake line?

Attach a flexible tube to the bleeder screw at the top of the wheel cylinder(caliper) of the affected wheel Put the other end of this hose into a container filled with clean brake fluid Have an assistant push the brake pedal down approx. 2/3 of its travel

Open the bleeder screw

Observe the hose in the container for air bubbles

Close bleeder screw

Repeat until no air bubbles are observed in container MAKE SURE MASTER CYLINDER DOES NOT EMPTY DURING THIS PROCEDURE

Where do you place jack to change front tire?

You should put the jack on the frame like it says in the instruction manual, but its hard to do from there i would suggest that you should put it on the axel, it may or may not work, i have not tried it, but its really hard to push the jack up on the frame.

When do you change brake pads and rotors?

If they are warped, they need to be turned, if they are groved, they need to be turned. If they are glazed, they need to be turned. In general, if you are working on the brakes, they need to be turned.
If they are too thin (not wide enough across) to be turned, they need to be replaced. Many newer rotors are not thick enough to be turned, so you just replace them every time you replace the brakes. Most auto parts retailers will measure the thickness of the rotors for you and tell you if they can be turned.

What is differences between mechanical and hydraulic brakes?

mechanical and hydraulic are two different power transmission medium.

in mechanical brakes solid links or levers are used to achieve the required braking.

in hydraulic brakes there are no links, here the braking is achieved by the hydraulic fluid, the hydraulic system in which the force applied at the brake pedal is multiplied several times to achieve the requied braking.
