How To Replace Brake Pads
-Axle Stands (EUR20 approx per set of two)
-Socket Set (EUR50 for an adequate set)
-Wheelbrace (Should be included in your cars repair kit though investing in a Metal cross would be worthwhile).
-Fresh brake Pads EUR30+
-Hydraulic Jack (you will need a proper main jack in conjunction with some axle stands
Pad removal checklist
-Procedure -Check?
Loosen wheel nuts
Jack car up
Remove wheel
Examine braking system
Remove Caliper, Slide away from wheel
Open caliper pins, release brake pads
Check Brake disc for damage
Prior Preparation:
-Always park your car in a suitable area with adequate workspace when attempting a brake pad change. Secure the Handbrake and disengage gear to neutral, prior to jacking the car up.
-Now block the cars rear wheels so it won't roll once you jack it up onto the axle stands!
-Spread your tools out and select a wheelbrace, moving to one of the front wheels. The wheelbrace is a metal bar with a socket on the end for removing wheelnuts. It will usually come with your cars toolkit, however if you don't have one, a socket set purchase will be necessary!
-Its always a good idea before jacking the car up, to loosen the wheel nuts first, whilst the car still rests on the ground. Usually the nuts will be tight, so trying to loosen them whilst the wheel is in the air will create some problems, (i.e. the wheel will keep spinning around!). Grab your wheel brace and proceed to loosen the nuts, however don't take them off fully, loosen them just enough until they can later be removed by hand.
-Jack the car up in a suitable, supported area of the cars chassis. Recommended areas to jack the car up will be detailed in your cars, owners manual. Make sure you use the chassis as a jack point for trying to lift the car! Never work on a car which has been elevated by only a hydraulic jack. Place both axle stands under each end of the main front axle, lowering the car onto the stands
Removing old brakes:
-Now that the car is supported firmly on the stands, you can progress to remove the wheel! The already loosened wheel nuts can be removed by hand, and when taken off make sure to place them in a cardboard box or in a drawer so you can find them at a later stage!
-Remove the wheel slowly and place it under the cars door nearest the wheel you are working on. You can never be careful enough when working on a suspended car, in addition to the axle stands and jack you are using, its always a good idea to have that wheel there, in case a faulty axle stand, broken jack etc lets you down and could result in the car falling! Taking these small yet extremely relevant safety steps are extremely necessary.
-Now that you have removed the wheel entirely, a brake system assembly should be visible before you.(or if not your in trouble!). The braking system consists of a brake caliper, two brake pads and a brake disc.
-As the diagram illustrates, the brake caliper is attached to the brake disc. Inside the caliper are two brake pads which need changing. When you press the brake lever in your car, the caliper will squeeze the brake pads onto the brake disc, in turn slowing them down, and effectively then the wheel. Imagine a CD spinning around, where a hand then from either side clamps onto it slowly, that has the same principle as the braking system.
-There will be bolts which fix the caliper in place and prevent movement. Remove these bolts (spanner size requirements will vary on different cars, investing in a socket set is again advised!) and take the caliper away from the brake disc. You should now have the brake pads within vision through the caliper.
-Examine the caliper closely. On different cars, brake pads will be held in by contrasting methods. Clip pins usually fix the pad into place, so when you remove these pins the pad will be released and can then be removed. Follow this procedure and remove the old pads. While you are examining the brake pads, glance over the brake disc also, if it has any grooves or chips in it, it will need replacing.
Replacing with new pads:
-Now that you have removed the old brake pads and are ready to replace with new pads, firstly check you have bought the correct size and model! Compare the new with the old, and once satisfied progress to place the new pads into the brake caliper, and make sure they are put in the right way!!
o Pull quote for pic: "Brake pad wear will be significantly increased on the right-hand side front wheel, due to added weight of the driver under braking."
-In putting in new pads, you will have to push the caliper piston back in, in order to fit the new pads in. The piston is usually a round face which pushes the brake pads in when the brake lever is pressed by a cars driver. When you would have earlier took the pads out, the piston will have opened out. This can be slightly tricky, so try pushing it back in with the heel of your hand firstly. If that doesn't work you can try an flathead screw-driver to gently prise the piston down and back into original position.
-Repeat the above procedure, though in opposite motion. Ensure that the piston is back in place, fit the new pads and put the clips back on which hold them in place! Remount the caliper back on to the brake disc. When this has been completed check around the caliper and bolts to ensure everything has been completed successfully.
-Find your wheel nuts which earlier where placed in a box, and place the wheel back on. When lined correctly, place the wheel nuts on, only by hand. Remove the axle stands and release the Jack slowly until the car rests on the ground. Grab your wheel brace and tighten the wheel nuts. Hey Presto, you have a brake pad change, but wait, theres the other front wheel! Repeat the procedure on the other wheel.
When you have completely finished both wheels, before you go driving make sure to pump your brake lever inside the car or you will have no brakes! Press the brake lever up and down, this will force hydraulic oil back into the braking system, which will push your
