4x4 squealing rear brakes

My partner has been complaining of noise from the rear breaks, I took it to my office today which is 50 miles, over half by motorway.

At first there seemed nothing wrong, but after 20 minutes and then on the motorway the rear brakes started high pitched squealing. After 2 hours of this today I now am a nervous wreck. It stops briefly when I dab the brakes but then comes right back on.

The rear brakes have always been a bit squeaky when manoeuvring, but this is a whole different ball game.

The car is just over 2 years old, we have had it from new, apart from this it is a great little car.

Before I get onto the dealership, do any of you have any tips on what I should be requesting? It seems I am not the only one affected here.

Thanks,

Dan

Re: 4x4 squealing rear brakes

May relate to the 'honking when reversing' noises (which they all make) - seems to be a lack of anti rattle backing (or Copperslip) on the back of the pads. I've found I can cure the noises when reversing by, every now and again (when safe, etc) pulling the handbrake on while moving forward at about 20mph: this seems to 'clean up' the pads and cures the noise for a couple of days. Maybe will help you too? Also though, some cars (not sure if Panda does) have a little 'tab' of metal on the pads that touches the disc when the pads are worn, causing a squeal that's supposed to alert you to the fact new pads are needed...

Re: 4x4 squealing rear brakes

Mine started to get a bit noisy and feel gritty after around 6 months.

Then it started honking and groaning when reversing as the pads were catching.

I rang the dealer and they weren't too eager to book it in, all that "bring it down, we'll have a quick look" I've fell for before!
Some salesman telling me "they all do that" after wasting half a day getting there.

I was certain I knew what was wrong so on a quiet Sunday I removed the wheels myself for a quick look.

First off, the calipers were built up dry, not a dab of brake grease anywhere.
They were also very dirty, they were caked in brake dust, road dirt and a bit of off road debris.

I cleaned them off and greased up the pins, everything was freed off.
I greased up pad backs and pad mounting points and thats worked for about 12 months.

Recently I can hear the pads "slap" back and forth in the calipers.
It's most notable when reversing, when I apply the brake a knock is heard from the N/S/R wheel and same again the first time I brake after pulling forward.
This is the pads gripping the disc and moving in the mounting bracket ever so slightly.

At around the same time, the O/S/F pads developed a knock over bumps.
Again the pads are rattling slightly in the mounting bracket.
It only happens over large sharp speed bumps (if I mount them with a little brake on, it doesn't do it).
As I know what it is I'm not too worried at the moment.

I'm fairly confident in saying the brake consumables fitted to mine are typical Fiat items. Cheap and uncheerful!

They've never fitted a decent discs or pads to any of their cars from the factory in the 35 years I've been buying them.
I'm just going to keep cleaning them off when they honk or squeal until they need replacing, then fit some decent Pagid discs and pads.

Yours will just need cleaning and greasing, if you can't wait for the dealer, try a "free brake check" from one of the well known chains, bung the spanner jockey a drink to clean and grease them up for you.

Re: 4x4 squealing rear brakes

My 4x4 TA's done 28000 miles in two yers and I haven't had any rear brake noises. the same was true of my Mk 3 100HP, a model that also gained a reputation for noisy rear brakes. I suspect it's because I very rarely use the handbrake as the car spends most of the time in a level garage.

Re: 4x4 squealing rear brakes

Our 4x4 TwinAir brakes had to be cleaned at ~4000miles and have just developed the Panda-"Honk" again at approaching 8000miles. I may do as suggested and give them a clean as described above this time, as it'll be quicker to do myself than drive up to the dealer. It sounds as if Fiat's insistence on a dry assembly may be the culprit...

Re: 4x4 squealing rear brakes

Fiat have a modification for the rear brakes that should be fitted under warranty. The dealer calls them rear caliper dampers. I'm not sure what they are but they were fitted to my cross about three or four weeks ago and since there has been no noise from the rear brakes.

Re: 4x4 squealing rear brakes

The rear brakes on my TA Cross are noisy in reverse & sometimes in slow moving traffic.

Dealer had a look at them at c1k miles but it never went away. Feels like they're binding which could account for the lousy fuel consumption I get from this car.

Is that an official fiat description that I can quote to my dealer in the knowledge they might know what I'm on about?

Re: 4x4 squealing rear brakes

The service report states:

Carry out modifications to rear calipers as per Fiat tech instructions and test (fitted vibration dampers).

Your dealer should be aware of this.

Hi. Has the remedial work stopped the brake noise permanently. I gave up trying to get mine sorted after two strip downs and cleans with fiat. I just live with it now but it's really annoying. My car is 3 years old in April so if there's a chance of a long term fix I'll pursue it.

Re: 4x4 squealing rear brakes

Since the 'vibration dampers' have been fitted sometime in September I've had no recurrence of brake squeal, or any other noise. It seems to have done the trick.

Re: 4x4 squealing rear brakes

I'm going to call the dealer to see about getting my brakes looking at after Paul's result .
I'm fully expecting to be told "sorry, the manufacturers warranty is only 2 years, and the third year insurance warranty doesn't cover that"

Hope I'm wrong though.

I'll do the same but surely if its been reported (& supposedly cured) on previous occasion it'll be covered. Won't it?
