Vauxhall’s corsa D model has a common fault with the brakes not working on the left front. This may not be a easy fix. But there is a likely cause. But before we go to common fault we need to be sure it’s not any of the obvious things.
Firstly check the sliders on the Caliper carrier and make sure the pads are free to move in the carrier. Doing this obviously eliminates these and could potentially be the cause in normal circumstances.
Next, see if the piston on the caliper pushers back easily. If you find this difficult you will think you have found the problem. Seized caliper? Maybe! I’m guessing not!
To eliminate the caliper and brake flexible hose being blocked temporarily refit the caliper and loosen the Union where the flexible hose goes to steel brake pipe. Now press foot brake and see if any brake fluid comes out. If it doesn’t you can guarantee the fault is further away from the caliper.
I have found the next thing in line to the master cylinder is the abs module. This is where the common fault is. You can confirm this by loosening the feed pipe into the abs module and pressing foot brake again. You will most likely find there to be plenty of fluid escaping.
Now you have found the fault you have a few options.

Now you have found the fault you have a few options.
- You could replace with a second hand unit from a vehicle breaker. Probably the cheapest but no guarantee. So may need replacement again in the future.
- Buy new from a vauxhall dealership. This option is very expensive but will be guaranteed for 12 months
- Have the corsa D Abs pump unit repaired by a reputable repairer. Many of the give a lifetime guarantee at a fraction of the price of a new one from vauxhall
My personal opinion would be option three. You can fit and forget with peace of mind it won’t fail again. If it does you can simply return to the repairer.
