As per title , i just change my stock toyota brake system (2pot 1pot ) into aftermarket Brembo (4pot 2pot)(recondition brake calipers) along with new Brembo rotors n Brembo brake pads (400cc). the problem i'm encountering it's the brake squeal whenever on a low speed nearby to stop...(mostly about to reach a traffic light)..the sound came in on n off...is it normal for a brembo brake to squeal? car driven from KL ---> JB ....JB ----> KL after change brake kits..clock more than 500km for now..brake still squeal ...any solution ?

thanks for all sifu sifu ! :adore:

Here I attached the video of it

Sounds like it is binding or can try sand paper the pads slightly. Sometimes work, sometimes the sound comes back.

davidcnz,
Several factor can take into account as your concern.
Probably you may get the fake Brembo rotor and pad as they flooded in the market.
If you getting the Brembo pad less them RM1000 each set, then its fake coz not from Italy.

Brembo kit (original) will squeal whenever its cold due to lining characteristic.
After awhile it will the squeal will be gone or after it reach warming up temperature.

i have try to check with 2 mechanic..they told me that the rotors n brake pads it's still new (as said the brembo brakes pad contain some metal in it , that why it have sound when the pads touch the rotors.)..but the sound will gone off after a week or two...

after the kits , i been driving the car from kl to johor ...then johor to kl ...approx more than 500km had been done ..but the sound still there...tat why i try to get some info around ..see if i can work out any solution or not ...

anyways, thanks for the solution..will give a try !

appreciate it

Is your discs lipped? If it is, maybe thats the problem. Just follow what VR2 said.
I think its not because of caliper issues.
Read nicely woh! people new rotors leh......:biggrin:

But sometimes new pads can be noisy, because done before, took out sand slightly then okay, but sometimes won't work....hahhaa

since the pads are new then maybe that's the problem, hopefully after a few more kms the sound will disappear

brembos are known to squeel, but I didn't know they'd squeel that loud. That's insanely loud.

I suggest swapping the pads to something with less metal content and try again. And like what pangyau said - there's the issue with the price of the calipers and all - the fake ones might not perform up to standard.

Brake making squeel noise normally due to the brake pad material... And... most of the performance brake pad will make noise when it still cold... *look at the disc.. if the brake material containt un-even (Got hard and soft compound) The disc will worn unevenly.. if this happen.. better change ur brake pad before too late... :smokin:

its doesnt make any squeel when it's cold on both surface (rotors n pads)..my problem it's the squeel sound out only when the brake pad n rotors it's hot...n i guess mostly its the brake pads problem..anyhow..i'm still in testing for the new pads to be worn more ...or else, i guess i need to change the brake pads b4 CNY :D

anyhow , noted bro..thanks !

My wife's SUV front brakes squeal very loudly when she reverse out in the morning. After that all quiet. Disc after 4 years still nice and smooth. However the rear disc have worn in quite deep and with one round of pad change.
So it is hard to be certain whether squealing brake means bad wear??

Most likely u were given racing or high temperature brake pad,they tend to squeckk/squeelll. Just get the normal OEM pad or OEM replacement.But you can't stand the brake dust later. Make sure use the grease and the back padding given with the pad.

The grease help to minimize the vibration between rotor/brake pad/brake pad shim/brake piston,Thus stop squeck/squeeling.
It doesn't mention in the internet but I think 2nd reason for greasing/shim is because since pad have some slight lateral movement in the caliper,by greasing the brake pad,it will just glide when pressed by piston caliper so it doesn't give lateral force to the brake piston,it may damage the piston caliper.The piston should see clamping force only(not lateral)

thanks bro..anyhow i just went to the workshop today..mechanic recommend me to sand the pads for the 1st try...(will change the pads for me if 1st try not workable ) so brake pads being sand on the side edges... even on the way back home (tried few "jammed brake" n keep braking to warm the pads) ..no more squeal sound .. ! :biggrin::biggrin: let me try few more miles ahead n see how thing goes :D ..

Backing plate suppose to make the pads more fitting so less movement so less noise.
As for the grease, if apply, just a little only and if possible use high temperature grease, if not if will melt. Apply to much and it might get onto the disc...

That is good news. Sometimes a small spec of sand stuck in between will cause the noise. Sanding clears it and no more noise...:driver:
