Do these discs look bad?

[chris.mas]

Hi guys

First ever post on here! And just looking for a little advice. I purchased a car from a dealership and noticed all 4 discs were rusty/ corroded, apparently from being sat outside waiting to be sold. Up on test driving I experienced a feeling similar to warped discs

They dealer agreed to sort the problem. On hand over day I see two new shiny front discs, great! Then I am told only the discs have been changed. And was also told the rears would clean up after a few 100 miles.

Well the brake pedal still feels "loose" and not how my other car feels, or anything else ever driven. I have also recently driven the exact same model and the brake pedal felt normal.

After aprox a little over 1k miles the discs look like this...


Would I have a case to get all discs and pads changed?

To me here is what a normal disc should look like

Some people have strange expectations.

Nothing at all wrong with them.

Just odd how the brakes feel different to an exact same model. Even my wife commented. She doesn't normally notice anything

I would have expected the pads to have been changed at the same time. I once had this disc only thing from a bike dealer, new pads sorted it

It certainly wont be the discs.

It would be expected that new pads would be fitted at same time as new discs...but that would depend how much material there was on the pads. If fairly new it would be a waste of money doing it

As for the feel.....if this is just after fitting the new discs etc...sometimes they can feel a little off for a few miles until everything is bedded in.
But without feeling it etc...no way to tell from here.

Were the original front discs scored? It looks to me as though the wear pattern of the old discs is being reproduced on the new discs because the old pads have been re-used. As for the rears, not pretty but the corrosion isn't, in my opinion, bad enough to affect performance - probably nothing more than an advisory on an MoT.

The 'feel' of the brakes is more likely to be down to the brake fluid or the servo. It is unusual to change discs without pads though, especially given the cost of pads.

Couldn't see if the original dics were scored as they had so much surface corrosion. Do you think if I fit new pads, these new discs will end up being fine? Or will they also beed changing....again

Yeah that is the general feeling, they were more than likely saving a few pennies by just doing the discs. Fluid looks at the correct level. I read somewhere that contaminated pads can cause an abnormal feeling in the pedal. Or even tracking, according to one site.

Without replacing both pads & discs you get into a vicious circle where the scoring is transferred from the old to the new. Having said that, while the front discs don't look very pretty, functionally they are fine.

I just can't understand why they have replaced the discs & re-used the old pads. The discs are the more expensive parts & labour costs are just the same to re-fit old bits as to fit new.

A though on the rear discs. You haven't said what the car is. . . not by any chance a Peugeot or a Citroen? On some, if not all, of their cars the rear discs can't be separated from the hub so replacement involves changing the complete assembly. As the new assemblies are usually supplied with bearings already in place it's an expensive operation - at full retail price you're looking at £150-plus for a pair of discs!

[chris.mas]

Yeah its a Peugeot. Would have imagined the rears to have cleaned up more than that with use? But then again the front brakes do more of the work I suppose.

I got quoted around £150 for the front set of discs, and around £60 for pads from main dealer. Euro car parts stock 2 different size discs. When I asked the parts guy what size mine are. He said the system didn't show that but "only the oem ones will fit" but then he would say that 🙄

Yeah that was my thinking, risk just changing the pads only to then spend more money if the become bad from the discs

It isn't the cosmetic side that bothers me. It is the feeling when applying them.

[PositronicRay]

When you say "they don't feel right" what do you mean?

Are they spongy, not sharp enough, not enough stopping power?

[chris.mas]

Seems to stop fine, but when you press the pedal. It feels loose and chattery. One of those things that is hard to describe unlese you feel it
