Brakes

Hi is there a way to adjust disc brakes as you can on the drum brake adjuster please

You don’t need to adjust self adjusting brakes. Even drum brakes have been self-adjusting for about the last thirty years!

As Oliver says, you cannot adjust them but.......Why do you feel you need to adjust them?

Hi As the brakes have all been renewed and bled I was going to see if the shoes could be adjusted in to improve things.All work done at garages but we still had air out so belt and braces

sorry don't understand your problem ,if the brakes are not ok take it back to the garage,but what is the fault. Further explanation needed.

That garage has closed.I will check the shoes are set close enough.

Drum brakes use ‘shoes’. Disc brakes use ‘pads’.

There is no adjustment on DISC brakes as the pads are always in contact with the disc, because the piston just has the pressure taken from it leaving it where it stops.
That's why when you drive off in a Disc Brake car that's been parked for a few days you often hear a slight rasping noise as the pads rub the surface rust off the disc.
That's why DISC Pistons have to be pushed all the way back in, sometimes using special tools, when replacing Pads.

DRUM brakes have adjustment, and/or self adjusters, because they have springs to pull the Shoes away from the Drum when the pressure is released.

As said above disc brakes do not have any adjustment, the seals are designed to pull the pistons back a tiny amount when the pressure is released, this compensates as they wear, new parts can have a bit of extra travel until the pads bed in but it should not be excessive or feel unsafe. The rears do have a significant effect on pedal travel though so yes make sure they are adjusted.

Other things to check are the master cylinder pushrod adjustment (should be a small amount of free travel ) and the master cylinder is not sticking.
