Hi,
As the title says . . .
my 2010 2L diesel Forester is getting the rear brake disc (in diagonal from the driver) hot.
After half an hour of driving I touched it with the tip of my fingers through the spikes of the wheel, and for 3 weeks I had blisters on the tip of my fingers.
Just a second of touching and it burnt me.
All the other 3 wheels were as cold as ice.
This has gone for a long time.
But because of the Covid we aren't allowed to drive far from home, I just kept going.
2 weekends ago I took care of the problem, or so I thought.
The took apart that brake.
The pads were obviously bare metal, all worn off.
In fact because of that I stopped driving, and just rode the bike to work and back for 2 weeks, until a nice weekend allowed me to work on the car.
The caliper piston was stuck.
I was prepared for this, and I've already bought a repair kit for all the calipers.
So I took the caliper off the car, let the brake fluid drip into a bottle, and dismantled the caliper completely.
The piston was full of rust just around its middle section.
Threw it away.
cleaned the insides of the caliper, replaced the seal, fitted the new piston, and new rubber protection.
Now the piston was moving nice in and out of the caliper.
Put it back on the car, both slide pins have been removed, cleaned and regreased, new brake fluid, bleeding the system.
4 hours job.
Checked the brake disc every day and is still getting hot.
Not that hot though.
You can touch it and even keep your fingers on it now.
But the other 3 are as cold as ice again.
Two weeks later and I thought the new pads are getting warm until they'll settle, but is still too warm.
New thoughts are getting into my head now:
The next move I'm considering is throwing away this car and getting a new one . . . just need to win the jackpot and I'll do it.
Anybody's got another suggestion?
Thanks.

New thoughts are getting into my head now:
- is it the hill assist brake faulty?
- anybody knows how this is working? - which wheels are locked when active? - is it perhaps the rear wheels?
- are the brakes linked to the head lamps adjust, as the front sensor is faulty and that could tell the brakes is on an incline, and such the hill brake assist would stay engaged all the time? But this could be the problem only if the hill brake assist is on the rear wheels, and working through the normal brakes, not through the parking brake (anybody knows better how these work?)
The next move I'm considering is throwing away this car and getting a new one . . . just need to win the jackpot and I'll do it.
