Technical Brakes again...

are you sure the bed in was followed ?

pads have a rough surface on them to clean up discs

"New brake pads do not provide full performance during the first 100 to 200 miles (200 to 300 km) and must first be broken in ⇒View attachment 407241 . To some extent, you can make up for the somewhat reduced performance by applying more pressure to the brake pedal. But, during the break-in period, the stopping distance for hard braking and emergency braking will be longer until the brakes are fully broken in. Avoid hard braking and situations that might require hard braking (such as following other vehicles too closely) – especially during the break-in period."
These pads were on the car when we bought it so I dont know. The score was a huge lump of what should bescintered metal material. Faulty pad. May be someone fitted non ABS pads. I usually take the car for a few days and ensure brakes and tyres get run in so normally the answer would be yes.
 
I dont know but there are different pads with and without. May be due to the intense cycling of the ABS system
This makes no sense at all; the ABS isn't cycled, except in rare emergency braking situations.

It's possible that non-abs models use a different pad/caliper design, and hence have physically different shaped pads, but that's not anything that's inherently a feature of having ABS.

Brakes are simple

But you do have to fit the correct parts

A far as I know there are at least 5 different pads for the fronts including

Diesel
4x4
1.1 and 1.2
Dynamic

According to Ferrero catalogue there isn't a difference for non ABS

Along with 3 different rears

Bendex, Bosch, Lockheed
Bendex = no ABS

I am just in this nightmare ordering the rear drum and shoes

Being a 2011 they changed from Bosch to Lockheed, but I have AP shoes and Bosch drums, pretty sure the drums are original and shoes are original

Im about to do the rears on our 1.2 and this has sounded a warning as that is also 2011. Thanks for the warning.

Maybe Ive been labouring under a massive misconception for many years. Ive had so many occasions where apparently the same car / pad have had ABS and non ABS pads. Ive always asssumed it was the pad as the discs were the same across all models. You learn something everyday.

I stripped and inspected before ordering

My drums are well worn, but the part number is the same as the Bosch system

These are cheap

The brake system is suppose to be Lockheed, I don't know if the drums are suppose to be the same as the Bosch system or not.

But sellers are selling Lockheed/delphi drums at £60-80 each

Two out of 4 of these clips were partly rotted away

With UK 3 day delivery

The best I could find was

£9 Lockheed accessory kit
£22 Lockheed shoes
£33 for a pair of drums

Then I lost interest in searching further

I couldn't find a full assembly for the Lockheed for a reasonable amount
 
Interesting discussion this. I'm thinking there are many brands of brake parts, especially when you start looking at aftermarket parts. Premium names like Girling, Brembo, Lockheed, etc. which often command a small premium in price and then Apec, EBC, Mintex, Bosch, ATE, etc, etc. which are more likely what I'll be buying. I bet they pretty much all make parts for our FIATs? Years ago I found local trade factors sell me stuff from trusted brands at prices which rival those on the internet so, for many years now, I've tended to buy from them. Now and again I'll check on line, but there's seldom any real advantage. Only very seldom do I have problems with wrongly supplied parts and it's very easy to pop back and get them changed if this does happen. Where there's difficulty in identifying a part I just take the old one with me and a bit of paper with the vehicle reg no and VIN.

I'm not aware of any difference in friction material for ABS systems as against in a non ABS but I've sometimes found two identical pad recommendations except that one has a wear warning wire whereas the other may not. The set without the wire is often usefully cheaper so I would tend to default towards that set - all other things being equal - as I check our cars so often the wear indicator becomes almost redundant. In fact, over the years, several of the vehicles in the "family fleet" have suffered damage and/or corrosion to the wiring and/or connectors in the pad wires. It can be a real "pain in the bum" trying to repair this - connectors are not easily available and often come complete with part of the loom at great expense. Of course the system activates only when earthed so isolating these wires doesn't result in the dashboard light illuminating and have no repercussions in terms of trouble codes or for MOT so I just secure any loose wires and forget about the system altogether.
 
Well I bit the bullet today and Daffo is booked in for new calipers front disc clean and a full overhaul of the rear brakes in 10 days time. I still cant face a day bent double so I will have to pay up. Ive told the garage to replace anything thats not 100%. They said the right things, its only 30K since the rears were replaced with new shoes and hydraulics and we both think its unlikely the drums will need doing or indeed the shoes so just clean and adjust with luck and if the calipers dont make the discs stay rust free the car will be on notice ! My new exhaust, fitted in a rush is blowing where the centre meets the back sections so thats to be done too and then and the MOT. I hope that before too much longer I can get back to it.
 
For the cost why not just put new discs on the front?
I'm wondering about this too. Absolutely no criticism of you Panda Nut, my heart bleeds for you, I know just how you must feel as I'm finding my aging body and associated aches and pains are now impacting considerably on what I can manage to do. However, new discs aren't that pricey and there would be little by way of extra labour charge to do them at the same time, so I'm puzzled why you've gone with cleaning up the old ones?
 
They really are fit and forget, until they wear

When the pads get thin, change them

When the discs get thin, change them

They are maintenance free

Here the thickness of my discs from the photo above paper thin at 7mm probably the originals from 10 years ago, they have been on at least 5 that I know of




The pads need to be nice and loose




They should come ready shimmed no need to add grease anywhere




If the slide err slided and the boot is intact it does not need touching

Fingers crossed they will not need touching for another couple of years and then only for new pads

They seem Farr to loose looser then any pads I've seen

I've always had pads that stay in place but only need a light pressure to pull in and out certainly no movement when inside the carrier

There absolutely fine there is only a few thou clearance

Pads are straight out of the box

This is against the fitting instructions that come from most pad manufacturers

Must move freely

IMG_20230914_131039.jpg



Most of the problems people suffer here are due to the fact the pads aren't free to float and follow the discs surface or able to push back when the disc heats up and expands causing them to get hot

Along with incorrect grease

pagid pads often have a drip of paint one lug from where they were hanging to dry

Fitted properly, bedded in carefully they are fit and forget

Freeze to move didn't mean loose

But perhaps it's just the video especially the sound can often be distorted by phones
 
They fiat pads are held by springs on the caliper, so there is a tiny bit of movement when the caliper is off.
Others with the sprung metal on the lugs have no free movement.

Well they are only 10 months or so old and only about 6000 miles on them. I was looking today and the N/S is seemingly good its polished up after my last work but the off side has a 7mm band round the outer edge where the pads just arn't doing anything. I think a flapper wheel will be able to clean the rust away if the back side is no worse. I will tell the garage to change the discs if there is more corrosion or uneven wear. You are right and it would probably best to start afresh I can get the discs refaced properly for the next time. The brakes work OK apart form a long pedal which may well be lazy adjusters but I know the dust seals are damaged on the calipers. I wish they had just left the adjutment manual. I have never had a rear brake adjuster that worked for long. The pistons are free as I always give them a good work out / in and our when the pads are changed and they ahve been cleaned and checked twice since hte discs were changed, but once the seal is gone its only a matter of time till they will stick. Its not much more costly to change them than do a re-seal job. Garage say they will use TRW calipers which should be OK I have to say I have little expectation that this will sort the issue I think its just bad engineering. On the health front I am slowly getting better but back to hospital in 10 days as I may now have a gall bladder problem. I wish they'd just dive in and cut out and chuck out all the old bits, lumps and growths in one go! I would if I were a surgeon. It cannot be effective to do only part of the problem and keep going back. I suppose that comment should make me see sense and do the same here!

That must be the 312 or 100HP?? The good old 169 has no such luxuries the pads are just hanging in the caliper bracket. The really annoying thing is I can see absolutely nothing to cause this rusting issue. The slider pins do have a rubber collar sleve. My suspicion is that the rubber goes soft and allows the caliper to flex and this then causes the brakes to effectively stick. When you check it all out with no load it would all work just fine, as indeed it does
