Hi, i have a Merc 416 cdi i`ve just taken it for test and it failed on handbrake efficiency, it only reached 10% and it needs to reach 12%,i`ve replaced all the handbrake cables and renewed the rear shoes,the discs are only 10 month old,i`m a little stuck as to what i could do next to reach 12% and get my much needed mot,thanks in advance Allan

Shoes may need bedding in to the old parking brake drums. Try applying the parking brake (gently) whilst on the move, don't leave on for too long or you will overheat the shoes and drums. Do this a few times and you should find the efficiency improves.

Thankyou for your response,i tried bedding them in on the way to test and think it did a little bit of help,this is its third fail now on this handbrake,first it was 8% then 9% and now 10%,so now i`ve put another new set of shoes in,new drums and a complete new handbrake cable,i`m going to take it out bedding them in then i`ll see if they can be manually adjusted anymore.
