Dam Sticky Brake

[bensyer]

near side front brake sticking, took off pads and cleaned it all up, still sticking , looked at the slider pins? and one of them was a bit stiff, cured that but that was not to fault.. so im guessing its one of the pistons then, when i pushed them in slightly the top one was a lot stiffer than the lower piston,, so is it possibly this thats to fault,, would a good clean solve the issue? pads are about 60% warn and disk has about a 1mm lip...

thanks in advance

Hi,

Lexus do a complete brake service kit ( I know it's around £40.00 for the LS400) or I have used a company called Biggred ( not sure on the spelling).

I'd open the gaitor around the pistons and get some WD-40 in there. Work the pistons back and forth with a G-Clamp and pressing the brake pedal until they move freely and then lubricate the pistons with some lithium based grease. Job done!

Just be careful not to pop the pistons out of their bores or damage the gaitors while doing this.

The best thing to do is either to put something where the brake disc would sit to stop the pistons travelling too far out, or put the caliper back over the disc each time you want to extend it. Just remember to secure both ends of the Caliper, otherwise it could pop off the disc.

I use a rolled up rear car mat to stop the pistons travelling too far, which works well.

HTH. :)

well it defo a sticky piston could hardly push it in with a g clamp really had to put all my mite into moving the darn thing , other one was fair easy,, any way in out in out kept loobing and cleaning , it was very dry with some bits of rusty crap in there,, good clean and a good lube its not as free as the other one but you can easy wind it in with a g clamp now witgh no effort , so see how tht gos, fingers crossed its done the job, will have to look into efurbing them or replacing them i guess

That should sort them out, at least in the short term. A refurb would definitely be a good idea, as if there's particles inside the boot they could damage the bores.
