Changing brakes i dont know how to change brakes so i attempted to do so and snap one of the screws the bolt is already completeley loose but i broke it and still cant get the calaper off to change my brake pads

usually down to a snapped cable usually seized mechanism and it is fairly easy to get the bonnet up, first if you look up under the front of the bonnet you can see the two bolts that hold it in place, then using a ratchet, extension, universal joint and a 13mm socket you can undo the bolts and lift the bonnet enough to then release the catch or cable, it can be a bit tricky to do,Also the cables have a habit of coming off the release handle, if you remove the handle held on by 2x 10mm bolts and see if it is still attached. i am going off a fiat as i do not know what car it is,

The rotor is not bolted to anything untill you put the wheel on although the caliper bracket does keep it from being removed i think only 2 bolts for the caliper bracket and 2 for the brake pads. If one is broke it must be fixed right away.

Drill a hole down the center of the bolt and use a bolt extractor

I just did my front brakes on March 7 2014 broke all bolts by hand except 1. Took my tire put it under the car and put a 15mm socket attached to the bolt and put the jack at the end of the wrench and started to pump and by golly the bolt came loose.

TO CHANGE FRONT BRAKE ROTORS. FIRST YOU NEED TO SAFELY RAISE SUPPORT VECHICLE ON JACK STANDS.MAKE SURE VECHICLE PARKED ON LEVEL SOLID GROUND.YOU NEED TO REMOVE BRAKE CALIPER BOLTS AND THE CALIPER FROM THE KNUCKLE.DONT LET CALIPER HANG BY BRAKE HOSE USE A PIECE OF WIRE TO SUPPORT CALIPER.REMOVE THE DISC BRAKE ROTOR RETAINING SCREWS IF EQUIPPED.IF THE ROTOR WILL NOT EASILY PULL OFF,SCREW TWO 8MM BOLTS INTO THE DISC BRAKE REMOVAL HOLES AND TURN THE BOLTS TWO TURNS AT A TIME TO PRESS THE ROTOR FROM THE HUB.

dont do it if you not confident some of the bolts are hard to remove and require heat to swell the metal to brake the corrosion, its not the best car to start learn how to change beats on, but if you do attempt it there is a small locking key on the drive shaft pulley it will fall out when you remove it, keep it in mind and dont lose it or you are screwed.

you will see a hole which is theaded on drum, slacken hand break cable, then screw a bolt into the hole, this will push off drum, dont no what size bolt is, you can buy a selection cheap at b.q

In the past I have had to use a 1 inch impact to brake that bolt loose. It is a monster and it is regular thread. If you dont have a big compressor and super impact I have held the engine a made a breaker bar and broke it loose that way and make sure to keep spraying it.

Open your trunk, you will see 2 screws that retain the brake light lens. Pull the felt on the side down, and you will see 2 plastic snap in clips. Remove the 2 screws and then use a pair of pliers to compress the plastic snap in clips to release them. From there you can remove the lens and replace the bulbs.

it is a torx bit for your caliper bolt.a size t50 if I am thinking right. use a good one as these can be hard to get broke loose.as far as rotors remove cliper slide bracket with an 18mm two bolts and rotor will slip off. might have to tap with a hammer
