Removing breaks from a 2000 Hyundai Accent

Hi from uk the 17mm bolts you mention do not remove as these secure the caliper carrier and only need removing to facilitate disc/rotor renewal to remove caliper only if you check the rear of caliper you will see two 13mm blts top and bottom of caliper these bolts pass thro conveluted rubber boots into slide pins bolts screw into these pins and the caliper is what is known as floating caliper this means only one piston operation on caliper then caliper slides on pins tou operate both pads when brakes applied so remove the two bolts and the steel spring on front face of caliper ?(remember how it fits !) then caliper slides off the rotor leaving pads in place on the carrier you then prise out pads/wirebrush carrier points where new pads are to fit then push caliper piston back then refit caliper in reverse order ADVICE= before refitting caliper smear alittle copper grease on rear metal side of each pad this prevents squeeling of pads when braking also pull out the to pins mentioned above that fit into carrier top/bottom wipe clean and put /smear copper grease on these too then refit and push in till rubber boots reseat on the carrier lips ? when you have done both sides brakes bleed calipers this is a must ! and when you do you will see dirty fluid emmited on the fist couple of pumps on b/pedal then clean fluid ? this WILL improve b/pedal travel and more positive ? the dirty fluid is o/heated /burnt fluid which becomes compressable giving soft pedal when operated and is due to heat transfer from disc/pads over time and is conducted thro caliper piston to fluid that is why it is recommended you bleed/flush hydraulics at least 2year intervals hope the above helps you and understandable best wishes from uk
