I'm trying to replace the front disk's of a Chevrolet Kalos
I presume it's just release the brake caliper ,then undo the large nut in the centre of the disk and take off the disk ????
Sorry I've chosen a Chevrolet Aveo, but Kalos dosent appear in the list and I've been told that the Aveo is the nearest thing to it

jack up rear wheel making sure you place a choc in front of front wheel, remove the wheel, remove the brake caliper there will be 2 bolts at back of brake disc you will then be able to undo then centre nut to remove the disc , if replacing disc it is best practise to replace both sides and renew the pads at the same time
replace front axle shaft you need to loosen axle nut with vechicle weight on the wheel just unloosen axle nut dont take axle nut all the way off just loosen it enough first remove hub cap to loosen axle nut.once loosen then raise vechicle remove wheel tire.you need to remove loosen brake caliper bolts just move brake caliper out of way support caliper piece of wire dont have to disconnect brake caliper hose just move it aside let it hang with a piece clothe hanger or piece or cord dont hang caliper by brake hose will damage brake hose.you need to remove brake caliper mounting bracket.go ahead remove axle nut.you have to remove steering knuckle bolts pull steering knuckle out of the strut bracket.you can remove front axle shaft by using large pry bar to the inner cv pry inner cv joint use a little leverage front axle should pop out.when you install new axle shaft push it in place until you hear it snap in place try pull by hand make sure half shaft in place. when done axle nut torque is 191 ft lbs.strut bracket bolts torque at 133 ft lbs.if this is your first time working on vechicle let a garage do the job.but buy the new shaft then take it with you for garage to replace be cheaper take own parts help cut down costs for part just pay for labor.
Replacing the front wheel bearing/hubs can be a big job for the inexperianced. Briefly...
Remove brake caliper assembly, do not remove brake line.
Remove caliper bracket.
Remove brake rotor.
Unplug ABS sensor.
Remove the large axle nut.
Press axle out of bearing (may need special tool)
Remove the 3 bearing bolts and remove bearing.
If you're asking how to, it's not overly hard with a spring compressor. First loosen the front lugnuts. Then jack the car up, apply the parking brake and chock the back wheels so it cant move. Lower the car back down onto jackstands and then remove the wheel.
Remove the brake assembly and rotor as if you were doing a brake job, except dont tie the caliper to the spring, tie it off to the A arm. Undo the 2 large nuts connecting the strut to the knuckle, but dont remove the bolts yet. Put your spring compressor on and tighten it down. Open the hood, and undo the 3 nuts holding the strut in place. Go back under and push the 2 bolts out, and the entire thing will come off in your hands.
Swap the springs over, wipe down the strut brace on the inside and reassemble everything using these instructions going backwards.
Drive the car to the shop of your choice for an alignment and you're done.
This is quite a job if your not a mechanic. I did mine a year ago. With the front wheel still on the ground you need to crack and undo the large axle nut on the outside of the brake disk. Jack up and secure whole left side of car. This will tilt the vehicle so the oil wont drain out of the transmission. Remove wheel. Undo 2 large nut and bolts at the bottom of the strut. Makes job easier aswell if you undo brake caliper and remove off disc and also the tie rod end off the arm. This will allow more movement to remove the driveshaft. Pull the hub assembly outwards and push the axle end back thru and out of the hub. After this comes out you need to pull the axle out of the transmission with either a sharp pull or you may need to pry out with a large screwdriver. When fitting new axle into transmission, make sure the gap in the circlip is sitting at the top and down inside the groove si it wont damage the seal on the way in.
Hope ive helped you.
Replace the flex line the rubber line between the car and the caliper. The inside of flex line can collapse making the back flow to release the caliper extremely slow. You can confirm the line is the problem by doing two tests. Pump the brakes up and undo the line at the caliper and it should release the caliper. Pump them up again and then undo the flex line at the steel line going to the master cylinder this should not change anything. Let me know if your findings are different and we can go from there.

Assuming that this Model has 4 Wheel Disk Brakes I will lead you the Best that I can. Remove the Tire, From there you will see a Large Disk with a "Caliper" Mounted on the top side that covers Both sides of the Disk. On the Back side of this "Caliper" on the Top and Bottom of it There is going to be a Bolt on the Top and Bottom. Some use Allen Wrenches and Some use Bolts or Nuts, Feel around and figure out which one you have. Remove these and Lift the Caliper Off of the Disk,BE CAREFUL WITH THE BRAKE LINE ATTACHED TO THE CALIPER AND DO NOT REMOVE THE BRAKE LINE! Remove the Brake Pads from the Caliper at this Point. On the Back of the Brake Pads that you just removed there should be Clips, Take these off the Old pads ans Install on the New Pads. Right where the Pads were on the Caliper there is going to be a Round Cylinder with a Large Hole in the Center, This needs to be Depressed back into the Caliper to get this Job done. On the Top of the Caliper there is a Small Bolt that is Round on Top and has a Small Hole in the Center Just like a Persons Head on a Nut. You MUST do the Next Steps Together to make this work CORRECTLY! Get a Wrench that fits the Small nut on top and Loosen it VERY LITTLE While you use a Pair of Channel Locks to Compress the Cylinder Back into the Caliper. You should see Brake Fluid come out of the Head in that little Nut. Once the Cylinder is Compressed Back into the Caliper Tighten the Little Nut Back down. Try not to let Air get Back into the Hole in the Nut that you are Loosening Or We will have a PROBLEM. So, Make sure you do BOTH of them at the Same time (Loosen nut WHILE Compressing Cylinder with Channel Locks). Install the New Brake Pads on the Caliper the Same way that they came off. Wipe everything off and keep it all Clean! Install the Caliper Back on the Disk and Replace the Bolts on Top and Bottom of Caliper. Get in the Car and Pump the Brake Pedal until it gets Firm and go to the Next one! This will work for all if you have 4 Wheel Disk Brakes. If you get two much air in the Lines the Brakes will go to the Floor and you will have to have a Helper Pump the Brakes while you Loosen the Little Nut on top of the Caliper.
