The braking system on your vehicle is the most important safety feature it has. The importance of being able to slow down or stop in an instance avoids accidents and prevents injuries. The braking system on your vehicle needs to be working correctly and effectively. In order to do the job they are designed to do it is important they are well maintained. 
It is recommended brakes should be regularly inspected and we recommend letting us test drive your vehicle to ensure the brake system is functioning as it should be. Here at All Trans Autos Ltd we offer free visual brake checks.  
To perform a complete report, measuring brake pad and discs thicknesses: checking for uneven wear of brake pads and brake shoes: checking all hardware is correctly adjusted and lubricated: Checking for leaks from Wheel cylinders, brake pipes, brake master cylinders: Checking the brake calipers for wear, free movement and free from leaks.  
Brake fluid becomes weaker over time, as it boils the brake fluid absorbs moisture. this can decrease the efficiency of the hydraulic components of the braking system. If the hydraulics are not working with maximum efficiency it can make the pedal less responsive, this will cause a slight delay and or a reduction in braking power. 
All of the components which make up the braking system need to be working correctly for the vehicle to have 100% effective brakes. All Trans Autos Ltd recommends a brake check every 6000. If your vehicles brakes do not feel right then just call in and we will check them for you. 

Brake Pads   

Brake pads convert the kinetic energy of the vehicle to thermal energy through friction. Two brake pads are contained in the brake caliper, with their friction surfaces facing the brake disc. When the brakes are applied, the caliper clamps or squeezes the two pads together onto the spinning brake disc to slow/stop the vehicle. When the brake pad heats up due to its contact with the brake disc, small amounts of its friction material are transferred onto the disc, leaving a dull grey coating on it. The brake pad and disc (both now having the friction material), then "stick" to each other, providing the friction that stops the vehicle. 
Types of Brake pads 
There are different types of brake pads, depending on its intended use. Most vehicle manufacturers specify which kind of brake pad is recommended in their vehicle. Care must be taken when fitting non standard brake pads to a vehicle. Here at All Trans Autos Ltd we only 'Original Equipment' quality, ensuring the brake pads fitted meet the specification recommended by the manufacturer of your vehicle. 
Five of the most important characteristics that are considered when selecting a brake pad material are as follows: 
•The material's ability to resist brake fade 
•The effects of water on brake fade (all brakes are designed to withstand at least temporary exposure to water) 
•The ability to recover quickly from either increased temperature or moisture 
•Service life as traded off with wear to the brake disc 
•The ability of the material to provide smooth and even contact with the brake disc or drum 
•Non-metallic materials - these are made from a combination of various synthetic substances bonded into a composite. They are gentle on brake discs, but produce a fair amount of dust, thus having a short service life. 
•Semi-metallic materials - synthetics mixed with varying proportions of flaked metals. These are harder than non-metallic pads, more fade-resistant and longer lasting, but at the cost of increased wear to the disc/drum which then must be replaced sooner. They also require more actuating force than non-metallic pads in order to generate braking torque. 
•Fully metallic materials - these pads are used only in racing vehicles. 
•Ceramic materials - Composed of clay and porcelain bonded to copper flakes and filaments, these are a good compromise between the durability of the metal pads, grip and fade resistance of the synthetic variety. Their principal drawback, however, is that unlike the previous three types, despite the presence of the copper, ceramic pads generally do not dissipate heat well, which can eventually cause the pads or other components of the braking system to warp. However, because the ceramic materials causes the braking sound to be elevated beyond that of human hearing, they are exceptionally quiet

Brake discs  Modern cars have brake discs on the front wheels. Some modern cars have brake discs on all four wheels.  It is the Brake discs which actually stops the vehicle.  The brake caliper squeezes the brake pads against the brake disc, the friction between the brake pad and the brake disc slows the vehicle down.  Each time the car is asked to stop the brakes convert eh kinetic energy, produced by the car, to heat. the heat is generated by the friction between the brake pad and the brake disc. Most brake discs are vented allowing air through the brake discs to provide cooling.  The vents can be seen here on the picture between the two surfaces.  To see how the brakes work go to page; Explore your car and click on the brakes video. 

Brake Caliper  When you push the brake pedal, Brake fluid from the master cylinder creates hydraulic pressure on one or more pistons in then Brake Caliper, forcing the brake pads against the brake discs.  When the brake pedal is released, the piston seals retract the pistons allowing the brake disc run-out to kick the brake pads away from the brake discs.  Floating brake calipers move in and out relative to the brake disc and can one or two pistons.  To see how the brakes work go to page; Explore your car and click on the brakes video.   

Brake Fluid  Brake fluid is a hydraulic fluid used in hydraulic and hydraulic clutch applications in cars, vans and motorbikes. It is used to transfer force into pressure.  It works because liquids are not compressible in their natural state.  Most brake fluids used today are glycol-ether based, mineral oil and silicone based fluids are available also.  It is recommended Brake fluid is changed every two years to maintain the efficiency of the brakes. If allowed to weaken due to condensation it will reduce braking efficiency.  On MOST cars it takes about half hour to change the brake fluid, if you are not sure when your brake fluid was last changed here at All Trans Autos Ltd we can test the brake fluid in your vehicle and advise you if it requires changing.  To see how the brakes work go to page; Explore your car and click on the brakes video.  

Anti - Lock Braking system (ABS)  The ABS is an automatic safety system that allows a motor vehicle to maintain tractive contact with the road surface while braking. the ABS prevents the wheels from locking up and avoiding uncontrolled skidding.  ABS generally offers improved control and decreases stopping distances on dry and slippery surfaces; However on loose gravel or snow covered surfaces ABS increases braking distance although it still improved steering control.  ABS has improved considerably since its initial widespread use in production cars, they prevent wheel lock whilst braking and they electronically control the front to rear brake bias. Depending on its capabilities and implementation is know as Electronic brake force distribution (EBD), traction control system, emergency brake assist or electronic stability control (ESC)  At All Trans Autos Ltd we are fully equipped to diagnose, repair and replace all the electronic components of the ABS, ESC and EBD systems. with the technicians employed at All Trans Autos Ltd you can be sure of the correct diagnosis with the best equipment on all makes and models. Our equipment is equivalent to the main dealers but at a much reduced cost to you.   To see how the brakes work go to page; Explore your car and click on the brakes video.
