anyone out there know how to change pads on a 98 accent?

Hi!.........here`s a useful `How-To` :-
Brake Pad Installation
Cheers,
Nick. :)

Here is a tip for changing brakepads. Instead of using a "c" clamp to to retract the caliper, take the old pads off, put the new inboard pad in place, and position the caliper back on but do not bolt it in place. Open the hood and take the cover off of the brake fluid resevoir. then,put a prybar or claw hammer between the outer forks of the caliper, and the rotor, and pry the caliper away from the rotor until the cylinder is fully retracted. Replace the resevoir cover, take the caliper back off, and you will then be able to put both pads in place and easily get the caliper back on in the correct position. You will not need to bleed the brakes. there is little danger of damaging the rotor and no danger at all of dammaging the cylinder, as you will be using the brake pad itsel, and not a "C" clamp to retract it. Good luck. :D

I agree with everything said but wish to add two cautionary notes:
1/ Don't let any one near the brake pedal once the caliper is swung clear of the rotor (disc). If its pressed, the pistons which push the pads against the rotor will be ejected from the slave cylinder as there's no rotor to limit their travel. You will now definitely have to bleed the brakes having opened the hydraulic circuit to air. You will also have dust and other damaging contaminates on the pistons and seals.

2/ Less obvious but potentially annoying - don't forget that as the brake pads wore down the piston travelled further towards the rotor lowering the fluid level in the master cylinder. If the level had been topped up with worn pads and / or shoes in place, it will overflow when you push the pistons back to their starting points. Syphon some fluid out of the master cylinder or get someone else to monitor the level as you push the pistons home in preparation for fitting the new pads and / or rear shoes. If you don't you could waste time looking for an oil leak which will meanwhile damage your paintwork
