Just spent around $400 on getting my hand brake adjusted. I got it back and it had zero grab as if it was not on at all. I took it back, he re adjusted for free. I drive
home and get out, my rear drums are burning, black smoke the smell the lot. So he adjusted them like they were on with the lever off. I spoke to the mechanic he says he just cant get it right, its a crappy nissan system or something and he has seen nissans give problems with hand brakes before. Mate this sucks, i have a hand brake with very little grab on the one hand, and at the very same time is grinding away while driving on the other!!! has anyone had any experiance cause right now I just want the work ute working for me not forcing me to take days off work like today. Thanks guys.

Sounds like your mechanic needs some schooling. Mine is fine.

Is yours a tailshaft handbrake like the GQ's?

could be, the rear diff is a MQ/GQ diff. the brake cable goes trough a rubber balancer alowing the cable to move the same distance to both drums and then straight to each drum brake lever. do GQ's even have drum brakes?

Yup, early GQs had drums 88 models.
then it isnt a tailshaft one if it goes to both drums.
GQs have a hand brake just behind the gearbox, with the system working on the tailshaft.

mine also has the lever behind the box tranny area. i am confused with what you mean about the system working on the tailshaft. BTW do you think the brake shoes may be the wrong size, repco matched them for me and they look identical but all these problems amke me think the problem is bigger than a small adjustment

The actual brake drum for the hand brake is on the tailshaft RIGHT behind the gearbox

F4Phantom,
I cant imagine anyone charging 400 bucks to adjust a handbrake mate.
I think you got done bad somehow, but to be sure, I would get a second opinion. Someone like NRMA (
sydney) I dont know what state you are in sorry. They will give you a full report. Keep your receipts cause i think from what i read, you need to get this so called mechanic to fix the damage he caused.
Rear drums burning more than likely means they sre stuffed and your shoes would be too. If it was caused by his lack of knowledge, id make him pay for damage caused.
Cant believe a tradesman could do something like that, he would know they were too tight cause wheels would not turn OR very hard to spin while of ground.
Ange.

$400 sounds like he fitted new brake linings as
well. The correct way to adjust a handbrake such as yours is to deadjust or slack off the handbrake adjustment then adjust up the brake shoes until they are just touching the drums. You then adjust the handbrake up to the same adjustment as the drums. The reason it is done this way is because the hand brake is on a mechanical leaver and the foot brake is by hydraulic cylinders, when adjusting the foot brake the cylinders are forced back in and the shoes centred in the drums. If the handbrake is not deajusted first it can hold the shoes out from the hyd cylinders and when the foot brake is applyed the hyd pistons move out to meet the brake shoe and can cause an overadjustment. I think I got this right its been a long time since Tech school. If your brakes have been that hot you may have buggered the lineings. Seized brake cylinders could also cause this problem as the hydraulic pistons are forced out but not pulled back by the brake springs,hope this is of some help.
Regards Nav.
