Hi I am vortash the easiest way to change pads is first to buy yourself a Haynes Manual for your vehicle type and model , this will explain the best and easiest way for you to change your breaks , they go into quite fine detail and explain everything with excellent graphics or pictures . I have had a manual for each of my vehicles and have completed many jobs otherwise thought to be the domain of the specialist mechanic . You will find this book invaluable for other jobs also and it will actually save you hundreds of Dollars / Pounds .. However if you can do it this way maybe I can explain how I do it on my car ..
first remove the road wheel make sure the car is safely supported .
Remove the Cap to the hydrulic filler resavoir for the brakes . place a kitchen tissue over the resavior and place an elastic band around it to prevent contamination from dirt and dust .
remove the pad retaining clips from top of calliper usuually two spring pins running through top of pads and remove the top calliper spring ( usually a black H shaped spring under the spring piins .
With a heafty screwdriver gently ease the brake pistons back ( this is why you take off the resavoir cap to ease preassure ) once pushed back ease out pads and replace .
not forgetting to replace the anti squeal shims .
I do this on all four wheels and then ease the foot pedal a couple of times to re set the pistons ..
Doing it this way also means I do not have to bleed the system .. replace cap and you should be fit to go .
I then take the vehicle to have a pre mot done they check the brakes on a rolling road and if they pass then I know I have done the job right and can have my family in the car wiith confidence .. hope this helps Regards Vortash
PS if you have the non return system on your car you will need to release each bleed nipple to allow the pistons to go back .. use a non return bleed pipe on the nipple into a glass jar so as to make sure there are no air bubbles and make sure you keep the resavoir topped up providing you do this correctly there is no need to bleed afterwards as long as the resavior has not dropped below half way and you have used a non return bleed pipe . .. vortash
