Question DIY - how to remove rear rotors when they are stuck on parking brake shoes

At first sorry if some English wording and technical description will not be correct or hard to understand but English is not my mother language Second thing ... I'm not car mechanic, cars are just hobby for me and what I know about them I learned mostly from internet.

I wrote this DIY for you because I was not able to find on internet good tutor how to remove stuck rear rotors which were holding on parking brake shoes due to excessive corrosion on edge inside rotor near parking break shoes. I did this job twice first on Hyundai Santa Fe where I damaged/deformed backing plates and parking brake shoes and also at my current Sorento where I was more successful => no other damage.

I'm 2nd owner of that car so problem comes out from 1st owner who or his service ignored brakes maintenance.

Of course I tried on both easier way: release tension in brake cable, close brake shoes by adjuster as much as possible but still rotor was holding on shoes by extra edge built from corroded material. Rotor itselves had few millimeters free play on bearing hub and its screws.

But ... it was how to say BRUTE FORCE way necessary tool is angle grinder.

1. release tension in parking cables, there is setting mechanism inside armrest

2. through setting hole in rotor I closed shoes as much as possible by adjuster turning (in hole is rubber plug, remove it, adjuster is in bottom side of assembly so turn rotor hole to bottom side)


3. now put on all safety gear necessary for grinding and start cutting rotor by angle grinder all around, NOT SO DEEP just in thickness of rotor material !


4. when you are finished it should look like this

5. now you have clear view on braking shoes, adjuster, springs holding shoes and two pins (each shoe one) with some U spring holding shoes on backing plate, in my case you can see excessive corrosion on adjuster so I was not able to close shoes to minimum


6. remove springs, remove pins with U spring and adjuster => this will give free play to breaking shoes

For springs dis/assembly I made from one flat screwdriver this ... very handy ;-)


7. if you had a luck in step 6. you don't need to do this step like me :-/ even there was a free play of shoes I still was not able to remove rotor .. still was holding on shoes ... I had to cut off (by chisel + hammer) edge on rotor through small space between shoes where was originally adjuster

8. after step 7. I was able to finally remove rotor from break shoes , at second picture you can see detail of that edge from corroded material which prevented pull out rotor



9. rear parking brake mechanism and bearing hub

10. parking break shoes and adjuster, shoes had little bit damaged edges on friction portion due to my tries to remove retor in each step



11. I removed corrosion (by steel brush etc.) from most of parts, backing plate, bearing hub, parking brake mechanism in top


12. I cleaned also adjuster and greased it with copper based grease, assembled back springs (it is not easy job, that modified screwdriver shown as very handy) and also pins with U springs (also a bit tough job, you have to hold pin from back side of backing plate and insert U spring), if you want hold shoes on position use clamp

13. time to assembly new rotors and pads, at first you will have to return piston inside caliper to make space for new (higher pads), at following picture I chose a way with bleading extra breaking fluid under piston out from system through bleading screw, by clamp I pressed piston back



14. hurray almost done ... one side only :-/ of course I did also some job on braking caliper and other parts (cleaning, greasing of rods, greasing of points between pads and pad liners etc.) but this is not main topic (you can find many videos on Youtube about it)


15. from previous picture of the rotor and from this picture you can see that the rear brakes were not working properly, there were grooves on rotor surface, pads were stuck in guiding etc., different wear of rear breaking pads is not probably problem because after my job I observed similar wear also on new pads, more interesting is that I had to replace rear pads again after approx. 60.000km because right inner pad was already on its minimum height but front pads which I replaced with rotors one month before my job on rear are still on approx. 75% of its max. height


16. adjust parking brake (adjuster between shoes), I set it like there is already friction on 3rd teeth of raised parking brake, fine tuning can be done also by setting mechanism in armrest, bleed braking fluid from calipers if necessery to remove air voids from system


Used parts:
Rear rotors Zimmermann 320.3807.20
Rear pads Textar 2552001
Breaking fluid ATE SL.6 DOT4 1l

Just for comparison what I put on front:
Front rotors ATE 24.0128-0248
Front pads Textar 2435101

Here are rear pads after 60.000km about which I was speaking about in previous post. Now I'm runing on Brembo pads so I can compare lifetime. But as I said before it is strange breaking balance in Sorento and this information I have partially confirmed by Kia service that it is normal behavior

The set on the right indicates a sticking caliper slide pin...

Cliper sliding pins are ok, they are moving well. I'm checking them and regreasing each tire change.
