just towed my caravan back from devon esp light kept coming on when braking at slow speed .no problem with out the van on so I looked it up on here but this problem not found how ever umbongo said to check the brake fluid level this was low topped it up .problem solved thanks umbongo

Might be worth checking how much pad is left on the brakes if theres no leaks, the brake fluid drops as the pads wear the fluid fills the cylinders, topping up is fine but you may find that when the pads are replaced and the pistons pushed back the fluid will over flow from the tank.
