Brake Problem

[Hanso]

I heard this awful scraping from my left rear brakes this morning when I got home from work. It sounded almost metal on metal. Which it shouldn't be as I put my rotors and pads on my RS Four S earlier in the year. The left rear rims is filthy with brake dust, the other three rims are very clean is comparison.

I then though nothing too much of it, and drove from Canberra to Jervis Bay for a work course this week. My left rotor now has some terrible gouges taken out of the outer part of the rotor. While driving, it feels as if that rear left brake caliper is stuck on.

My questions are:

* Do I have a stuffed brake caliper?

* Can it be fixed by bleeding the line or am I looking at a new caliper?

* Is somethng stuck between the pad and rotor?

I know I will need to machine the rotor. Just shits me when I haven't had them on the car for six months. The rotors are Dixcel SD slotted rotors, the pads are Project MU B Spec's.

Any suggestions would be greatly appreciated. And if anyone can suggest a brake place in the Nowra area, that would be great too. I would like to at least hopefully stop the metal on metal sound enough to get home to Canberra Friday.

Cheers,

Hanso

I had a similar issue when one of the rear calliper sliding pins bent, not sure how it happened or why but it locked one pad onto the disk continuously. I would be checking it out before driving it too far.

sounds like a stone has got stuck in there but i could be wrong

oooh bugger.

I'd be taking that wheel off and pulling the pads out for good looksee me thinks.

Cheers, being on a training cse I don't have lot of tools in the Stag. I think I'll try a brake place in Nowra Fri arvo before heading home. I know that the rotor will need machining at least. I just don't want to be up for too much coin hopefully.

simular thing happened to me a while back

Just had a better look at the left rear pads, the are very worn compared to the right rear pads from what I can see. My paranoid frame of mind is thinking that the brake caliper has crapped out. Can you get them repaired or is it easier to replace?

Is the rear brake caliper the same for all model of Stagea's or do they differ between the series / models?

[gldwgn]

series 1 rear calipers are different

is the inner and outter pad worn similar or 1 more than the other?

if 1 is worn and the other's not to bad may just be the slides in the caliper not sliding freely,

if thats the case you should be able to remove, clean and regrease them.

I can't see the inner pad as I don't have tools with me to get the wheel off. Epic fail on my part.

I found out today that the workshop I got to install my rotors and pads only installed both the front and the rear right Project Mu pads. The left rear pad is some random pad, pretty easy to tell as it isn't aqua like the Project Mu pads. Now that I have got home to Canberra, it is down to metal.

I rang the workshop, and they are doing their best to back pedal out of this. I am ot giving them the option. As far as I am concerned, they owe me a Project Mu rear left pad, and at least a machined rotor, if not a new one. The rotor is really f*&ked up.

On further investigation this morning, the pad was correctly installed. The caliper piston was not disengaging properly. So a caliper rebuild next week plus new pads for the left rear brake. The rotor has been machined, I'm glad I didn't have to order another set from Japan.

I can't fault the workshop, their professionalism is fantastic. They opened up this morning so I could bring the Stag in. I was in a bit of a tanty last night with a few issues happening all at once, getting tear gassed at work didn't help either lol. I am definitely one happy customer and would recommend this workshop to anyone.

Thanks everyone who has offered their ideas on what the fault could be, SAU once again helps me out big time. I'll post how things turn out when I get my car back next week.
