    Default Jimny front disc shenanigans

    Hi All

    2011 Jimny

    Having had OEM front discs skimmed and new pads fitted at 67 000km mark upon recommendation of both dealer and independent brake outfit I am once more (at 75 000km) faced with a violent pulsing through the brake pedal and feedback via steering column i.e. time to completely replace brakes.

    A quote of R1850 a disc via dealership elicited a knee-jerk 'bugger that' reaction and I've since sourced a set of ALFA DR6101 through Autozone at R1100 (inc VAT) a piece ... and for a while I was somewhat chuffed at a perceived savings, until I tried having them fitted at Supa Quik. The technician informed me (and I witnessed) that the new disc would not fit on the wheel hub. The spigot diameter seemed just that bit too small and the disc could not be seated.

    Bemused, I called Autozone and informed them of the fact. I also double checked ALFA's website to confirm part number and indeed the DR6101 was recommended for Jimny's 2008 onward. Measuring up internal diameter of new discs there did not appear to be eccentricity and by and large the figure arrived at was 107mm as listed under ALFA spec.

    Ferodo's catalogued alternative to the OEM disc is a DDF351 - also of 107mm spigot diameter. Anecdotally, overlaying the existing vehicle mounted disc (once removed) with new disc, surface to surface, visually confirmed the one centre bore did not match the other.Searching the web I stumbled across this link http://www.bigjimny.com/index.php/fo...disc-size-help and perhaps the mystery is solved?

    It would seem that post 2005 (or thereabouts) Jimny's have 108.3mm centre diameters (as opposed to earlier 107mm centres) and that makes a world of difference. Perhaps there is a workaround? No doubt one could have a mm or two machined off by a machine shop but that seems extra palavah and cost.

    Perhaps I was just daft, didn't do enough research and made a rookie error. Heck, maybe my hubs have an issue?! Whatever the case, I do wonder if anyone else has walked a similar path in independently replacing their front discs? Perhaps this has been raised as a thread on this forum before, though a cursory search and read didn't flag this issue. If so, my apologies for rehashing. As it transpires, ATE has a model 24.0110-0355.1 that has 108mm centres and the search currently endures for these

    Perhaps this experience could be useful to someone ...

    Violent pulsing would indicate a possible issue with the ABS to me. Bleed the brakes all round again and check if the light flashes when applying the brakes but not hard enough for the ABS to kick in.

    All South african Jimny's have discs with a centre hole of 108.3mm.

    I fitted EBC discs, and they asked which hole size, 107 or 108.3.

    I just did the same thin over the weekend. Bought 2 discs from Midas make "Stone" for R322 per disc. The size of the whole was 107 mm. I measure the original and determined they needed to be 108mm. Luckily a family member with a steelworks could machine it out to 108mm. Only to find out they were still too small. So after measuring with an electronic vernier we saw that the correct measurement is 108.26mm. Machined them a bit more and they were 100%.Fitted them with TextAR brake pads. Brakes are working very well now.

    Nope... I had the same issue. Hot spots on the dics. Discs look 100% finr but you get quite a shudder under hard braking. New discs and pads work well

    The "Violent Pulsing" made me think of that. Normally people complain of vibrations or shaking etc and to differentiate between the two can be difficult to explain.

    Hi Guys,

    Did anyone find discs that are not from Power Brake? Also need to replace mine, and it is getting serious now.

    Regards,

    What I should have said was, has anyone found a set of replacement discs, that doesn't almost cost the same as OEM.

    I am looking for a Set of ATE's. I found some, but the inner diameter was 107mm.

    So the search continues.

    R2400 for the discs - I don't know what OEM cost.
    R700 for the pads - Much cheaper and better than OEM.

    I installed ATE on our Jimny

    or Well, I let it be put on.

    Midas Quoted me I think R960 per disc and HiQ Dastek Quoted me R 890 Per disk installed so I went that route. Had the same size issue although HiQ sorted it out on the spot with no extra charge. They just filled the excess off a bit with a electric Metal Round File.

    Obviously took them an extra 45 mins to fit them but I can't complain. It fitted and works 100% with no issues.

    P.S. Formula Friction are Awesome.

    If you have the Money Get yourselfs some GreenStuff, So worth the while only downside are that you need to wait 2 weeks for the pads. Talking about it I need to order another set to have them ready when I need them and need for my Caddy aswell

    That is what I have planned now. Bought a set of discs yesterday, having them machined out today. And then I'll fit them over the weekend.
