Last year i had my rear brakes replaced (discs, pads and seals) at a place in new plymouth while we were up north, since they done that my handbrake has made a ticking sound, my temporary fix was to just wind the handbrake back, making the handbrake pretty useless, heres a vid of whats happening

can anyone tell me what could be causing this issue and a possible fix

have you taken the disc off yourself and inspected the handbrake mechanism? Sounds like something is out of alignment ie the retention springs or the bottom adjuster are out of alignment

by **loudstealthGT-Four** » Sat Sep 17, 2011 12:42 am

Ive pulled them off multiple times haven't seen anything out of the ordinary (the problem is on the right and left rear discs) ive also pulled the entire handbrake assembly apart and put it back together and still have the same issue.

But to be honest i dont know what im looking for, Ive taken it into MIDAS in invercargill (my usual mechanic) and he said there was nothing wrong with them, so just adjusted them up tight again and on the way home the problem was so bad my brakes were smoking :evil:

, so i just loosened the handbrake off and left it at that.

The only thing i can think that (might) cause an issue is when they replaced the discs the shop that done the work couldn't find any discs for a st185 celica so he used discs from a caldina which he said were the same?

Can anyone tell me the specs for a rear disc for a ST185 GT-Four mainly the ID and depth of the handbrake part of the disc.

Thanks Tyler

How did you tighten it up?

Not sure on the setup on the silly cars...so this may not apply but I had uneven left to right handbrake on ae111. Loosen off the handbrake at the lever, disconnect the cables off the calipers, pump the pedal a handful of times, connect cables back up, adjust lever so it's just tight enough to not be loose when off and see how that goes. Before hand, one wheel would spin and the other was locked solid when handbrake applied. Afterwards both wheels were locked solid with handbrake on, so worked a charm. Credit to Crispy86 for that.

Different problem by the sounds, but could be something else to try.

But if winding the brake off fixed it.... then it could be related. The adjustment at the handbrake itself isn't for adjusting the brakes I don't think, more so for just taking up the slack of the cable. Make sure the cables move freely at the calipers too.

Ah ok, totally different setup then. Brakes are fun!!!

So after just discovering that part in my repair manual with the diagrams of the handbrake assembly, ive noticed something that may be wrong

on this diagram the anchor springs are illustrated to go through the hole in the shoe, but on my shoes they are held through the the slots?

will see if i can get them fitted through the holes instead of the slots, and see how that goes?

haha they are making me :evil:

Definitely been put together wrong, also check the adjuster is the right way around. It should be self adjusting and if the wrong way can interfere with the return springs.

celica and caldina shoes are the same. Parts supplier sourced me new shoes and they are from a caldina.
+1 for assembled wrong. Need to go through the holes

by **loudstealthGT-Four** » Sat Sep 17, 2011 9:10 pm

ok so after trying to fix the problem today (to no avail) :evil:

. I decided to go out to my parents place to look at the handbrake assembly on my old ST183 celica, and have concluded that the pins i was talking about do not go through the hole they can just sit in the slots (as this is how it was on my ST183 which has the same set up) and it was not possible for both the pins to go through the holes as they are not aligned

Im starting to get seriously frustrated with this #$@*ing issue as it seems like such a simple set up, but is so hard to diagnose

Will pull the whole assembly apart (again) tomorrow including the cables and see if i can find something wrong

righto - i've pulled parts out of the storage containers and will have a play around, but the large hole in the hub does point through to the slotted areas.
Of note, are the 2 pins which secure the pads in place.

Q: Is the bent pin on the pad with the lever side? If it isn't, that could be an issue as the pin is bent to allow for lever movement.

Yip bent pin goes on the side with the lever on it and the straight pin goes on the side with just the shoe

by **rollaholic** » Sun Sep 18, 2011 1:02 am

are the shoes on the right sides

by **DeeCee** » Sun Sep 18, 2011 1:07 am

well, I've assembled the shoes onto the hub carrier. They do mount via the slots, not the holes.

Listening to your video again, something def sounds loose. Assemble again and see how you get on. And I remember my little trick now. To get the top retainer off, use some needle nose pliers in the grooves, push down and twist to release. Reverse to put back on

by **LEAKER** » Mon Sep 19, 2011 12:59 pm

Mine does the same. for me its the retainer spring pin got bent out slightly and it touches on the flange. It's on the list:)

well last night finally got motivated to pull my handbrake assembly apart and see if i could find anything out of the ordinary, pulled the cables off and gave them a clean, they were in good condition. Cleaned all the other bits of the handbrake assembly and re-assembled it, gave all the springs and moving parts a spray with CRC, tightened up the handbrake.

Then this morning took it for a drive and the noise is gone. I still don't really understand what was wrong in the first place, but for now its all fixed and Im happy

by **loudstealthGT-Four** » Tue Oct 25, 2011 7:07 pm

Ok so last week after a good 3 weeks of this problem being sorted, it decides to come back :evil:

.

So I took it into Magoo Muffler and Brake on Friday afternoon and they took it for a test drive to see what the problem was, reckoned it might of been been the hand brake part of the rotor was out of round. So took I took it back in today for them to put it on the hoist and have a proper look, and turns out that the rotor was out of round.

So they chucked a new pair of rotors on the back and so I'll see how that goes

And on a side note, Thanks 'DeeCee' for going the extra mile to help me out, help very much appreciated

by **DeeCee** » Tue Oct 25, 2011 8:23 pm
