You most likely only need to change the pads on the front axle and either have the rotors turned or just purchase new (some cars new rotors cost about $10-20 more than turning so IMO a better option considering time and BS you have to deal with at the shop . Caliper (look it up) is the component that press the pads to the rotor and generally lasts for the life of the car.
You normally do both sides at the same time. As your caliper was now gouging your rotor, I (if I were you) would take it to a garage and let them do it. You missed the warning noises(a high squealing sound) which tells you to change the pads soon. You waited until it went to steel to steel - which now does not brake and also ruins the rotors.
. Some rotors cost $130 a piece(so you never want to damage them)...where the pads cost 50ea.
. Once you heard the grinding you know it is not good.
, Right now some of the caliper has seized up(sand and dirt does this occasionally) and basically has to be totally disassembled...or replaced with a new one.
No but changing both in pairs in the front is recommended and would probably save you time and money in the long run. I would go nuts- pads, rotors, calibers and bleed the entire system after starting at the furthest point from the master cylinder.
Calipers should be changed in pairs. If you need one front, you should do the other as well. You should also think about changing the 2 flexible hoses that attach to them.
You need to change both sides if you are working on the brakes (to keep them even). Here is a great how to video to show you what needs to get done and it is perfect for beginners!
no u do not go ahead and change the shoes
I think I only need to change the caliper on the front drivers side. Do i have to change the others as well?
