Patanga Posted December 3, 2008 Report Posted December 3, 2008 Hi... I have an AE82 twin cam (4 wheel disc brakes) and the hand brake doesn't work. The rear calipers have been professionally rebuilt, one new hand brake cable has been replace (adjustment at the handle end is working & both cables now pull evenly) and yet there is still very little hand brake function. As the rear calipers have been resleeved and overhauled I'd like to think this is not the problem. By the way, the hand brake was the same prior to the calipers being done. Has anyone had any experience with this issue on the AE82's or any suggestion as to what to do? Cheers... Quote

When the brakes were installed, was the handbrake adjusted at the caliper end? aka, you need to screw the actual piston out, to get the right clearance, so when the handbrake is pulled up, the brakes clasp.

Trev Posted December 3, 2008 Report Posted December 3, 2008 You should bring it to my house in ipswich. Quote
Patanga Posted December 3, 2008 Author Report Posted December 3, 2008 Thanks for the offer but it will be some time before the car will be on the road. It seems that the piston needs to be screwed out to get the correct clearance so i will try that first. Cheers Quote

Cheers The piston does not have to be screwed out, They are self adjusting, You just pump up the brakes and the handbrake location will be set. Quote
Patanga Posted December 3, 2008 Author Report Posted December 3, 2008 Hi & thanks for the tip. That makes good sense.. I'll give that a try and see how it goes... I appreciate the feedback. Cheers Quote
Patanga Posted December 3, 2008 Author Report Posted December 3, 2008 Ok It seems that there are a number of thoughts on the adjustment of the rear calipers??.... I have heard that the pistons do screw in and out to allow fitment of new pads. Many caliper designs work this way. What has me intrigued with this one is that everything up to the calipers seems to be operating perfectly. i.e. cables are free and are also even at the balance bar towards the hand brake lever end. To my way of thinking that really only leaves the calipers that could be in question. Before I do anything more I will get a friend to watch the calipers as the hand brake lever is operated to check for free operation of the actuating lever and then take it further from there. I'll let you know what I find. Cheers and thanks again. Quote
Bowler Posted December 3, 2008 Report Posted December 3, 2008 (edited) <retracted>. Just get some multi grips, and screw the pistons out. I had a similar issue when I did my brake conversion, and a mechanic mate had a look at it, and fixed it in 5 minutes - by screwing the piston out a little bit...

Trev Posted December 4, 2008 Report Posted December 4, 2008 the rear drums are self adjusting, but the rear disc models aren't. Just get some multi grips, and screw the pistons out. I had a similar issue when I did my brake conversion, and a mechanic mate had a look at it, and fixed it in 5 minutes - by screwing the piston out a little bit... FFS mate, I know what i am talking about, I work on toyota's all day everyday, Have several AE82's and know toyota rear brakes but if you know better go ahead. Quote

Trev Posted December 4, 2008 Report Posted December 4, 2008 look, i'm just goin off personal experience, and the 5 or 6 manuals all saying the same thing "PE" so only once. Patanga you only have to wind the piston in (clockwise) when you are putting new pads in, Under no circumstances should you have to wind the piston out, The brakes are already installed on your car so this shows that you have already done this, Just pump up your brakes a few times and the rears WILL adjust themselves (unless the ratcheting mechanism is stuffed) and you will be able to use your handbrake, If you want me to show you the CORRECT way I can come to you for the cost of fuel or if you want a second opinion you can call my workshop: Road & Track Ph: 32017079 Servicing & repairing the unusual is an everyday occurrence for us Modern performance; Toyota Corolla, Sprinter, MR2, Celica, GT4 & Supra Road & Track Bowler do some research before you give false information in the future.
