Brake issue - car just back from MOT - diagnosis?

[blueovercream]

I've just got my car back from having its rear discs and pads changed.

New discs and pads fitted, then it passed the various brake tests for the MOT without any issues

Halfway through the drive home it felt like the brakes were binding and the problem worsened as I continued. Once I arrived home both rear brakes were really hot. There's also minimal resistance in the handbrake lever, which I can pull up higher than normal. Hopefully my brand new discs and pads have not been wrecked by whatever is going on.

The garage, who I have known for a while and trust fully, are sending a truck to collect and have a look.

Can anyone speculate as to what I'm likely to be looking at here?

knowing what car it is would help, but it sounds like the handbrake shoes haven't been set correctly, assuming it has shoes on the inner of the disc and not using a separate calliper, are both wheels hot? ( don't touch the discs)

Could be a twisted soft brake pipe, it could be the shoes have lost a spring or retaining pin and have slipped jamming against the inner drum, could be bad connection on an electric handbrake plug or 20 other things, you need to ask your mechanic.

Rear discs or drums?
Chances are if it's discs they have just whacked the new pads in and not cleaned or checked the contact surfaces to make sure they are able to slide freely. I've fitted 2 sets of rear pads in the last month (different cars, different makes of pads) where they needed dressing a little to be a decent fit so they don't bind and cause the sort of issues you're experiencing.

If the parking/hand brake also operates the rear calipers then this sounds to me like the pistons were pressed back instead of being wound back in order to let the system recalibrate. The parking brake mechanism is settling at the biting point of the old pads and of course the new ones are thicker and so pressing against the disc constantly.
