Yesterday I had a good fortune to have a day off at the shop with a bay and a lift.
So since i had all of the parts to swap out my old EPB I went to town.
This job took me about 7 hours to complete.
I had new rear rotors new E brake shoes from Bilstien these came with a spring kit,
new EBC green stuff rear pads ,
and a new EPB unit procured from Island 4x4UK for 700.00 plus shipping.
I did run into a few snags
I would suggest to also have on hand 2 new exhaust gaskets and a new brake pad warning sensor.
The first hurdle was getting the rusted manifold nuts off.
I have a nifty induction heater for removing rusted exhaust bolts,
this worked on 3 of the 6,
the other 3 snapped off.
So after dropping the exhaust ,
i got my oxy acetylene torch and heated up the manifolds where the bolt heads are pressed in.
then got the air hammer and drove them out.
I went with removing all 6 as the 3 that had the nuts come off were in pretty bad shape.
I used a few wet rags to place them over any parts that might be damaged by heat.
Then i got 6 fresh bolts and nuts and washers , in lieu of going to the dealer to buy these bolts
this makes it easy to install and i used anti seize on the new bolts.
this caused about an hour delay to remove the exhaust and the 6 bolts.
Anyway the rest is taking things apart the same on both sides.
you will need all of 55mm drop to get to the EPB anchor bolts,
they are torx,
and make sure to drive the tool into the bolt hole or you can easily strip it.
The brake cables also have a boss that is sort of pressed into the where the cable mounts to the backing plate.
Spray PB blaster into the area where the cable comes out,of the backing plate
then after you have removed the bolt that holds the cable anchor to the backing plate.
get a small punch and drive the anchor towards the EPB unit.
NOTE if you try to pry from the backing plate side thats facing the EPB unit,
you can snap off the the boss that fits into the backing plate mounting port.
NOTE on the EPB unit,
Spray the elex connector with PB blaster then blow it dry with compressed air,
this will make it clean enough to open so you can remove the harness from the EPB unit with a long screwdriver pressed into the lock tab.
I would strongly recommend that you replace the rear rotors and shoes and pads and a spring kit whenever you have the first sign of the a parking brake failure.
This will restore the system to full function.
NOTE you will also need to unadjust the star wheels so the old rotors can easily be removed.
Put grease on every bolt you install so it will reduce the corrosion issues.
same for the cable anchor crimps at the EPB unit these are bare metal and will rust badly.
Use DC111 on the airline fittings,
black and orange are the colors to remove to empty the bags,
this after removing the RR wheel well liner.
after fitting everything back together ,
Use the tool to reset the accelerometer inside the EPB needs to be used,
then clear the codes then test the E brakes.
