Annoying brake noise help please

[den9112]

Hi, I have a 2018 Suzuki Swift booster jet and I have an issue with the brakes.

I will start with what I have done to the car up to the point of hearing the issue.

I changed the front discs and pads (Mintex) a couple of months ago and all was fine, but I noticed when doing so that the left and right caliper piston seals were torn a little but enough for it to bother me

However, in the meantime, I purchased two salvaged calipers from a low-mileage donor car. I cleaned them up and re-greased the slider pins and replaced them.

I am not sure how long after I replaced the calipers, that I was getting a creaking/groaning sound when the brake pedal was at the bottom end of breaking. When I kind of jabbed at the pedal it creaked both forward and reverse.

It does not do it in normal driving. I did a couple of emergency stops at 30mph and it stopped as it should with no noise. The car was due for the MOT so I thought if anything was wrong it would get flagged up. However, it passed with no advisories.

My next job was a gearbox oil change and that is when the creaking noise was a bit more obvious, as when I was coming back off the car ramps and I was slowly touching (jabbing ) the brakes to come off them, you could hear it more. It is like the pads are sticking and releasing

. It is like it is jabbing and then springing back is the only way I can describe it. I then stripped the brakes and replaced the pads with some Brembo pads and at the same time making sure everything was greased with the correct grease. I even checked the anti-roll bar bushes and all was fine there when I tested with a crowbar. If I pull up slowly and easily and stop, it won't happen, but if I put that end push on the brake, it creaks. Same in reverse as when it did when I rolled back off the ramps.Any help would be appreciated .

Why two threads ?

and paragraphs, please.

Two comments:

1) It's a common characteristic of many braking systems.

2) It's not a problem.

Exactly. Makes it too difficult to help.

You're here asking for help. Nobody owes it to you. The harder and less pleasant you make it to help you, the less help you're likely to get.

Somebody was letting you know your post was difficult to read. This will be putting off many people from helping you.

The constructive response would be to edit your post to be more readable.

Now it is a bit more understandable here are my thoughts.

You don't actually say where the noise is actually coming from.

I mention this because if it is from the brake pedal it could be one thing, if it is from the actual brakes it could be others (especially if it is front/rear/one side only) and if it happens when braking generally but isn't from the brakes it could be many others.

If you can't make your mind up which it is/isn't get someone else in the car to help narrow it down.

[den9112]

The noise comes from the front of the car and is more prominent from front offside wheel area mainly the caliper (brake) .

The best way i can describe it is in comparison to a push cycle when you squeeze the front brake on and off when going down a steep hill and you get the jerky squeaking noise,,, That's what it feels like when i do the same on the brakes only with my foot.

Maybe it is down to non OEM disks and pads..

[mercedeslimos]

I'd check the discs for runout with a DTI to start with, many non genuine discs are utter ste quality and warp easily, also did you clean the hub mating face immaculately first as this can cause disc wobble.

[den9112]

Hi Thanks for the reply.

Discs are the only parts I have not physically removed.

I may even change them for Textar OEM (same price as Mintex) so that's the next check/job

Really hard to guess what's going on without at least hearing it.

Is it due for a service any time soon? Getting an experienced mechanic to listen to it would be your best bet, if you can't work it out for yourself. If you ask the internet to diagnose it for you, you'll get suggestions covering the whole of the suspension and braking system and could waste a lot of time checking things that are perfectly fine. Worse yet, you might even introduce new problems.

Hi, i was hoping that something may have got flagged up when I took it for the MOT.

But yes I may take it in to get looked at probably save me a lot of hassle.

Did you reuse the calliper bolts/sliders or replace with new?

[den9112]

Hi
I used the existing caliper mount bolts 17mm if i remember correctly and torqued to 85nm as per manual.

I did replace the caliper slide pins and guides and used silicone brake grease on them as that was a no-brainer as I work just around the corner from brakes international and could just buy from the shelf...

[Dave Brand]

As I see it now you have two choices:

1) Carry on throwing money at a non-problem.

2) Live with it.

Just about any braking system can produce this sound under the right conditions of pedal pressure, speed, etc. It may well become less noticeable as the pads wear down.

[den9112]

Hi
Going to live with it for now as it did pass the MOT as it is
..
Also, it stops as it should maybe I am looking for issues when as you say most braking systems will make some kind of noise in certain circumstances, and to be honest there is not much more I can replace ....
