Pumping the pedal once pads have been fitted I always pump the pedal while engine running,
Did you push that screwdriver against the disc to push piston back?if so isn’t there risk of damaging the disc
There is not much force behind a properly functioning piston so the disc will be fine.
Did that insignia have locking wheel nuts,if so I’d never use an impact gun on the locking wheel nut,that’s my thought,no offense intended or implied
Can not remember, however I use the gun and if the wheel nuts do not spin off as they should I won't carry on with the impact, putting them on I just snug them up with the gun and then torque them up.
This video is vey helpful. I have the same insignia and i can t wait now to change my break pads myself. Thank you! Cheers mate! 😊
Glad it helped
