i have a hyundai 2011 i40 estate which i,ve had for a while, first Hyundai for me, always had Fords, mondeo's,
had a problem with N/S rear caliper sticking on, wasn't the EBS motor, but the piston, had pads changed in April this year, pistion really hard to push back, but garage managed to fit new pads, week ago N/S was down to the metal again, back to garage, this time would not go back, so only fitted new pads on O/S using old O/S pads on N/S just to get me back on the road, garage told me needed new or recon caliper,
priced these up, £150 + £100 surcharge refunded when they had my old one back, Hyundai wanted £313 inc vat for new ones, stupid money !!,
i,m a very handy guy, so i ordered a new set of seals from Bigg red £23, if i messed them up just buy a recon one,
this is what i did, DID NOT HAVE BRAKES WOUND BACK VIA PLUG/COMPUTER. brake off, wheel off, clamped brake pipe then removed, removed EPB plug, removed caliper, 2 x 14mm bolts, brought in house, removed motor, 2 x alien key bolts, used drill and tork bit to wind piston out fully, there is cog which motor sits on, then wound it back fully, removed piston, WATCH THE FLUID, unscrew the piston ram. then the sir clip from the cog at the rear of the piston, removed ram screw/cog, removed small seal for ram screw/cog, then piston seal, cleaned all parts, making sure seal groves are clean, replaced small O ring seal for ram screw/cog, replaced piston seal, replaced ram screw/cog, replaced sir clip, screwed down ram on threaded ram screw, lightly greased pistion seal with grease supplied, slid dust seal onto piston, pushed piston into caliper, dust seal is the tricky one to fit, bit of fiddling and it was in, when you replace motor, there is a rubber O ring that needs to be replaced before fitting, THATS IT !!, ALL DONE, replace caliper, replace brake pipe, replace plug, i fitted new pads, bleed fluid and thats it, no need to reset anything, parking brake works as it should, DON'T KNOW WHAT ALL THE FUSS IS ABOUT !!!!, done both calipers, working a treat !!!!,
meant to take pictures of it all but forgot : ( shame, really simple to do, no need to be plugged in and wound back, cost me £100 all in, new disc's/pads/seals/fluid, sorted,
if you need any help or have any question, please ask, thanks hope this helps !!!!!
