Brake pedal becomes slow to return

[Quimo]

Hi, I’ve recently bought a 2014 Octavia 2.0 TDI and I’ve noticed that the brake pedal looses its normal “slack” and becomes slow to release. Has anyone else had this?

I’ve looked up if it’s the servo but apparently diesels don’t have one?

Thanks for the help

When was the brake fluid last changed and the system bled?

Get a different manual; I've never owned a car with disc brakes that didn't have a servo.

Look under the bonnet to see if there is a servo.

I did some very light research, may have been a brake booster? Or is that a servo?

Doesn't look like that is going to happen 😁

Same thing, yes.

Diesels have a brake servo just the same as a petrol engine car.
They both use vacuum ,Where they differ is a petrol engine  produces a vacuum in the inlet manifold that is used to operate the servo , A diesel doesn't ,so to provide the vacuum needed for the servo a vacuum pump is fitted , usually on the end of the camshaft.

Ah I see!

thanks for that information. I’ll try a bleeding the brakes first then work my way up to that.

I would be surprised if bleeding the brakes would cure the problem, usually brakes need bleeding because the brake pedal is spongey .
