Title: Brake discs
Post by: Wabbitkilla on February 28, 2010, 13:44
Well my EBC disks are two years old nearly and the grooves have worn off the inside surface of the fronts so i'm now getting the bands of death appearing.
Not bad though, they have done a lot of miles.

So i'm looking at replacing them, but has the price gone up or something?

Anyway always on the lookout for alternatives i found Venom motorsport sell EBC and their own versions.

Has anyone tried their disks before?

Nick if you decide to stick with the EBC disks I bought mine from these about a month back and couldn't find them any cheaper anywhere else.

If it's any use as a reference point, Toyota charged me £61.29 per disc + vat in April 07 (Had me by the short and curlies).

How many miles roughly was it to kill the EBC discs?? Two years seems pretty short, but then i haven't run grooved ones until i got the EBCs.

I was going through this stuff after having a look at my discs yesterday. Mine aren't too bad, but was also thinking of replacing mine. I've noticed that the Mk1 and 2 chaps have more to choose from. Was looking at EBC Red Stuff pads, but they never seem to be available for both front and rear on the Roadster.
Interestingly my rear pads have worn down quicker than my fronts , not experienced that on this car before.

Ive noticed that about the redstuff pads, they only seem to be available for the rear and it seems to me that it would be a really bad idea to put ceramic pads on the rear and not the fronts.

First set op pads were black stuff, they were ok.
Second set were Greenstuff, they were better but take a little warming up.

Thanks for that link Ian, a little bit cheaper than i've found so far and i've ordered a full set with Greenstuff pads.

are rears needed?

I've ordered them as a precaution as i can see a bit of corrosion appearing in a band on one of the surfaces.

Better safe than sorry with brakes eh?  s:wink: :wink: s:wink:

Well, ordered online on the 28th Feb, still no sign of them.
Range them today and took ages to answer and he's checking with the wharehouse.

Interesting - I ordered from http://www.ebcbrakesltd.co.uk/ as they were even cheaper. This was on the 14th Feb and I was going to recommend on here, but then they didn't turn up until last week (4th March) so thought I'd hold fire on the recommendation. I had to ring them to chase, but they were pretty good thereafter about keeping me in the loop - apparently they had to wait for a batch of rears to come in from EBC overseas.

I can only find £82 on ebc site for normal discs but they're only £47+VAT on that other site for the 'turbo groove' ones. Am I missing something as to how to get them cheaper?

I need to get some soon as mine are getting pretty rusty now.

They've called me back.
Were waiting for a production run at EBC for the rear discs, i should have them on wednesday   s:D :D s:D  

They could have told me i suppose

£47 is for a single disc - but then they state you've got to buy in pairs   s:roll: :roll: s:roll:  Bit misleading really.

Yeah I got it was for a single, so the £82 price on ebc is for a pair? I couldn't see, if so I'll get them from there then. Think I've got about £450 of expense next month, 2 new tyres, discs and pads and getting my clutch fitted (£200 cash from local garage, bargain)

Still not arrived.

Waiting for the latest excuse and if they haven't been sent cancelling the order.
Luckily it's not so urgent as the car passed MOT... but they will need doing sometime this year.

Dam thats slow service, mine arrived in about a week from ordering.

Yeah, the problem is at EBC, waiting for a production run on the rear disks.
I'm getting a refund and will look into it again later in the year.

I'll probably ring EBC direct to find out if they're in stock at the time.

Camskill were very fast delivering a full set of plain EBC discs to me recently.

I'm currently in the market for some replacement EBCs - certainly a pair of fronts.

As a rare user of brakes I'm surprised how quickly the inner face has worn - 40k miles compared to 95k on my stockers which were still serviceable when they came off.

But here's the thing - the wear has been accelerated on the inners where the disks have warped, which explains the very crunchy braking that i reported a couple of months back. As a result, one of the three grooves has completely worn down while the other two are intact. Makes for some very interesting feedback through the pedal   s:shock: :shock: s:shock:  .

That said, the EBCs have held their finish really well compared to the stockers. None of that severe rusting around the hub and outer lip. OK, its not the first thought to go through your head when you're trying to stop, but there y'go   s:D :D s:D

My front EBCs are grumbling at the moment after 30k miles.  The outer face of the discs look ok other than slight scoring aroung the middle of one of them.  I was kind of hoping it just needs new pads rather than discs as well.  Is the '2 just heavy on the front brakes?
Title: Re: Brake discs
Post by: loadswine on April 5, 2010, 19:22
I changed my rear pads for a fresh set of Black Diamonds today.
The 2 outer pads had peculiar areas where friction material craters had formed.
Discs were okay, apart from the grooves needing cleaning out.

I've not had pads start to disintegrate quite like that before.

I'm currently looking at Brake Depot, they look quite impressive and pretty good prices including Greenstuff pads. You can have them Zinc plated in silver, gold, or black.

Nic - how are the brakes now they have been on there a few weeks?  Mine needs fronts and trying to decide whether to stick with EBC, go back to OEM or something else.  The rears look ok so tempted to stick with EBC and just do the fronts.

EBC turbo grooves are £107.95 on Camskill.

I ended up getting CRN discs, and they're doing very nicely ... a lot quieter than i was expecting. They have had about 2000 miles put on them now with the recent Scotland trip, and they performed very nicely up there in the wet and the dry.

I don't think i would go with EBC again as the dimples were forming into craters on the inside surfaces when i took them off.

I got a complete set of CRN 40Groove discs, Zinc plated, with Greenstuff pads for £200ish including delivery (may be a discount with being a member of another club). They advertise on eBay, on their own website and on Facebook ... nice people to talk to and deal with. Would be worth ringing them and talking to them.

After seeing Nigels pads above and the ones i took off mine i may in future consider using something other than EBC .. they work well enough but i didn't like the look of the surfaces. Still it could have just been the condition of the discs i suppose.

Changed my EBCs yesterday to another set of Turbo Grooves and OEM pads with the previous set lasting 32.5k miles.  The discs were scored and the grooves were pretty much worn off on the inner faces but I reckon I could have got away with just changing the pads.  The outer pad was only about 50% worn but the inner pads were pretty much down to the metal!
Title: Re: Brake discs
Post by: frogger on June 21, 2010, 19:12
Wear that uneven (between inner pad and outer pad) indicates that your caliper sliders probably aint quite sliding right 100% of the time.
I'd inspect the sliders for any signs or corrosion, and the slider seals for any damage.
If all looks good you could just clean everything fully and reassemble the sliders with a helping of red rubber grease (no other type of grease will suffice!).
If the seals look ropey, would swap 'em out for new ones.
Title: Re: Brake discs
Post by: Two's Company on June 22, 2010, 08:35
There were no signs of damage on the sliders or seals but I know a few members who have had problems with them.  The calipers could probably do with a refurb now it is nearly 7 years old with 82.5k miles.
Title: Re: Brake discs
Post by: Wabbitkilla on June 22, 2010, 09:47
Being single piston single sided calipers you will always get uneven wear with the pads directly in contact with the piston being hit hardest.
That's the problem with this non-optimal design, the only way to get even wear is to have opposed pistons.
Which produces problems with wheel clearance ... everything has a but   s:wink: :wink: s:wink:  

Yes, slider wear, corrosion and seizing can affect this, but if they look good then they're usually ok.
Plus with the "stone guards" on the back of the discs then there is increased corrosion on the disc surface making the inner pad work harder too.
