Hi there
I have an '86 Troopy and love her to bits.
Lately however when I pull the handbrake up she still rolls back and then when I release the handbrake the lever is completely loose. The handbrake still has not engaged though. One or 2 mornings I've found her in the middle of the road which is no good.
When I then go under the car and firmly push the handbrake lines where they split the lever tightens again and one can feel something 'unsticking' inside the hubs.
I've removed the hubs etc and cant see any problems. The foot brake works
well and I've bled al the brakes and topped up the fluid etc.
I'm no mechanic but was wondering if there is a simple solution before I spend more of my hard earned cash down at A1 Automotive.
Thanks for any tips!
Grant

Not being a mechanic myself but could the brake cable need tightening?? as it would become stretched after a while.

Hi Karl
cable is tight
something must be rusted in the hydrolics or something?
Time to bash the credit card I reckon
cheers

hand brakes are not hydraulic
they are operated independantly from the foot brake
check adjustment of cable and shoes. also check that the cable moves freely

As donks1 said, check the cables move freely, and you may need to take the hub off and check the handbrake lever/mechanism in the drum.
While you have the drum off, give it all a good clean with a blast of air, and relube.
Is your handbrake and brake drums self adjusting or manual adjustment?
Maybe the brake drums need adjusting as
well.
Sounds like your first indication that a bit of general TLC required for the rear brakes :O)

Cleaning a brake drum with a "blast of air" does not sound very healthy to me. I always clan them with fine
water spray to wash the dust out rather than propelling it with compressed air closer to my nose.
I too had a problem with my troopies handbrake, one day the truck rolled forward and knocked down the
closed gate in front of which it was parked. Fiddled around with adjustments and lubricated cables but it remained a non trustworthy handbrake.
It came good suddenly by itself! There is an automatic adjuster (HJ75 model) and I had a good look at it recently when I serviced the brakes. The exact operation of the adjuster remains unclear to me but somebody told me they self adjust only in reverse. Strangely, I have reverted to backing into my driveway for about the same time the handbrake came good, coincidence?
I can now confidently
park the troopie (engine running, handbrake on) in front of the
gate and close it, the truck stays put on the steep driveway.

The Toyota adjuster works each time you pull the handbrake on. The adjuster on old Holdens worked when you applied the brakes when in reverse.

Hi Grant,
Does your Troopy have rear disk brakes? I can't remember which year they where fitted.
If it does you'll find the handbrake actually operates on a small drum inside the rear of the disks. You can't see it by just removing the wheel, you actuall need to remove the disk and the handbrake drum comes away with it. They can stick or sieze due to moisture. Also if they've stuck on at some stage the handbrake shoes will be shagged.
Otherwise, if it's a drum brake model then there is a fair bet the mechanism inside the drums is corroded and sticking. There is a pivot where the handbrake rods terminate at the brake backing plate, this often sticks.
Also if drum rear brakes, check the adjustment of the brake shoes.
Basically it's a TLC process for the rear brakes by the sounds of things. If you don't have one it might pay to get a workshop manual for your Troopy.
Geoff.

Thanks for all the help!
Rear drum brakes - and there is a little cog inside with a lever that winds the pads out as the cable is pulled repeatedly. I take it this is the auto adjustment?
Anyway the cable doesn't move freely so I think that the pivot mechanism must be in need of a clean and lube
thanks again guys
have a good one

Same thing happened with the handbrake on my 60 series which sounds like a similar set up the Troopy. It was the short cable inside the brake that pulls on the drum mechanism that had stretched. No amount of adjusting the cable and shoes would make it work. Replace the stretched cable (both sides) and the handbrake was quite good for a Toyota handbrake. Brake place where I got the cables told me it was a common problem as the vehicle gets older and a simple fix.
