Replacement and checking of your brakes. 

Wherever you drive, brakes are essential for your safety. Whenever they are used they are put under extremely high stress. As the brake pads grip the discs the friction creates heat. This means that over time the brake pads and discs wear out. You will need to have them replaced once they have reached their minimum level of thickness. 
 
When you have your brake pads checked at Ignition Autos we’ll also check the condition of the brake discs. These tend to last longer than pads and generally should be replaced with every other set of pads. If your brake pedal feels spongy, or it seems to take longer than normal to slow down, then your brakes need to be checked urgently. 
 
Most Vehicle brakes work on an hydraulic system which multiplies the force of your foot on the brake pedal into enough force to apply the brakes and make the car stop. The brakes themselves are usually one of two types: disc brakes or drum brakes. 
 
Many modern cars have disc brakes on the front wheels and drum brakes on the rear wheels. More expensive models may have disc brakes on all four wheels. Only very old or very small cars tend to have drum brakes on all four wheels. 
 
If you are concerned about the performance of your brakes or would like them checked before going on a long journey please book an appointment and one of our technicians will complete a free, no-obligation brake inspection. 
 
 

Kentic movement 

Disc brakes consist of a brake disc, a brake caliper, and a brake pad. When the brake pedal is depressed, the hydraulic fluid causes the brake caliper to press the brake pad against the brake disc. The rubbing of the brake pad against the brake disc generates friction, which converts kinetic energy into heat in the brake pad. 
 
How much heat? A lot! Stopping a speeding car can heat the brakes to 950º F or more! To withstand such heat, brake pads must be made of special materials that won't melt at such high temperatures. Some of those special materials include composites, alloys, and ceramics. 
 
Drum brakes also use friction but in a slightly different way. Drum brakes consist of a brake drum and brake shoes. The hollow drum turns with the wheel. When the brake pedal is depressed, a hydraulic cylinder pushes brake shoes with friction linings against the inner surface of the brake drum, creating friction and thereby slowing the wheel. 

How do i know if I need to stop by?. 

Below is some common signs of braking problems that are tell tails you need to come see us to get things sorted!. 
 
Grinding - when the friction material on brake pads are heavily worn, this can result in a grinding noise as the brake pad has worn down to the metal caliper. This will likely damage the brake disc also. 
 
Squeaking - there are many reasons why brakes squeal. It could suggest the brake caliper has stuck and the brakes pad remains partially applied to the disc but some pads have wear indicators that squeal when worn to let the driver know the brakes need changing. Either way, you should get this checked out. 
 
Pulsating - If you feel a continuous pulsating from the brake pedal whenever you apply the brakes, this indicates the brake disc has become warped due to excessive heat. Pulsation occurs because the brake disc is distorted and no longer provides a perfectly flat surface when the brake pad makes contact. If this only occurs when you apply the brakes firmly, it could just be the ABS kicking in but you should have this checked out if you are concerned or it happens regularly. 
 
Pulling - if your car pulls to the left or right when you apply the brakes this is usually indicative of a sticking hydraulic or mechanical component such as a seized caliper. An inspection can identify the precise reason for the vehicle pulling to one side. 
 
Sponginess - the brake pedal feels spongy and the brakes seem unresponsive. This is a sign that air has entered the brakes lines and is preventing the brake fluid from flowing through this system effectively. 
 
Soft Brake Pedal - if the brake pedal is limp and goes all the way to the floor, this indicates a serious braking system fault which you should have inspected immediately. A brake pedal that is soft and can be applied all the way to the floor usually means the brake fluid is ineffective and needs replacing but there can be several other potential reasons such as a master cylinder fault. 
 
Lights on the dash - if a brake warning light appears on your instrument panel either continuously or when you apply the brakes it usually means the brake fluid level is critically low. This could also indicate a leak in the brake hoses. 
 
High Handbrake - If the handbrake is pulling up higher than it normally does it may need adjusting. In modern cars, this is usually anything more than 6 to 8 clicks. If the handbrake lever reaches the end of its travel it will fail the MOT. 
 
Old Brake Fluid - If your brake fluid is over 2 years old it may be losing its effectiveness since it has hygroscopic properties which means it absorbs moisture over time. This affects the properties of the fluid which negatively affects braking ability. Brake fluid should be change approximately every two years but check your manufacturers handbook.
