Month of Brakes – Brake Fluid and Pipes

okay so its the 3rd instalment and you guys have come in your droves to have your brakes checked!! I now know that half the drivers of Bridgend are coming to a stop!!

so we (I) have talked a lot over the month about discs, pads, drums and all that jazz so lets take a step back. lets ask the questions: “How do my brakes work? what happens when I press the pedal ?” …… I’m going to go as simple as I can because no one wants to spend their afternoon reading about how a servo or a vacuum pump works do they? and if you do Facebook me!!

so basically when you press the pedal brake fluid builds up pressure and pushes the pads against the disc causing friction and in turn causing the car to slow down, its basically a high pressure version of you sticking your foot out on to the road, when riding your scooter when you were younger.

 it builds up pressure by using brake fluid, brake fluid comes in different forms like dot4 and I think newer high performance cars have started using dot5 but I’m not sure of the difference in all honesty, but yeah, it travels down a brake pipe to the brakes and boom pressure is applied and your slowing down. now the reason I’m telling you this is, brake fluid has an actually fancy name that I cant even think about how to spell. it basically means it absorbs moisture due to it getting hot and cold as you use/don’t use them this plays games with your pedal and can cause your brakes to be spongy. its meant to be checked every service but some garages “don’t see the point ” so when you get a service if it isn’t by me make sure they check the brake fluid!! its meant to be changed very 2 years or 20,000 miles….. if you brake under normal conditions. if you brake hard or you find your self in a lot of traffic jams have it checked more often.

also you should check your brake fluid levels weekly just to make sure there is the right amount of fluid in there and there is no leaks. if the fluid is below the correct level check for leaks your self or call a professional.

those of you who own an old car will know how it feels to fail an mot on brake pipes!! well the manufacturers are so lovely and clever and thought “oh I know brake pipes run underneath the car, subject to flying stones, water and other debris.. they also have the chance to have water on the inside…… I know ill make them out of steel.. a metal that’s prone to rusting”    and this is why you would have failed an mot for brake pipes they rust and get pitted and because its under pressure they can burst and you have no brakes. luckily for you guys, garages or mobile mechanics like myself will fit a new copper brake pipe for you in its place (copper doesn’t rust). You get rubber brake hose to their more forgiving but if you change your own brakes make sure you don’t twist this or kink it in anyway. also some people say its okay but I personally don’t like to leave the calliper hanging on the rubber, because It CAN, (not definitely) damage the hose so in my opinion its best practice to secure the calliper to remove strain on the hose

so basically brakes are prone to failing in all areas of its design so that’s why its so important that you keep on top of them. if you don’t know how, give me a shout at http://www.facebook.com/ellsautocare  .I will check them over for you and show you how to check it your self!! that way in 12 months time when it needs checking again you can do it and save your self a few quid.
