I have spent the last hour going through the 16 pages of Braking on the forum it haven't seen this posted.
Our A LWB has drums on the rear and when you brake in a hurry the back locks up causing the back end to slide round which while it is fun I'm pretty sure it's not meant to do that.
The front pads are a bit low and I have a new set here to put in but I can't see that them being low will stop them not working.
Do these have an adjustable brake compensator as the guy before use to tow a trailer with his gig gear in so not sure if something has been adjusted to go with that or it's a bigger issue.
