Judder ..Judder

[davemo888]

        Hello All

 A question I hope can be answered


     Steering rack completely changed ,track rod ends  ball joints  etc

     front shocks changed

     brake calipers and slides changed  ( thanks again Tony, much appreciated.)

     But when I brake lightly ,there is still juddering ,felt through the wheel more so than the peddle.If i brake hard ...no judder
     
     Question is ..what  next ..master cylinder or discs or something I have completely overlooked

      any help would be appreciated

             Thanks   dave

Did you fit new pads ?
Did you check discs for grooves or warp ?

[davemo888]

New pads...  check

  discs    apart from rust around edges look good no grooves ,ran finger across, no apparant warp either

   total scratchy head moment

[Kernowman]

May be the pads need bedding in... or pad compound is a hard type.
This gives longer life but needs harder pressure to work.
See how you go with them... hopefully it'll settle down as they are run in.

Only other thing I can think of is worn lower ball joints... but should be same when breaking hard too.
Or wishbone bushes are worn... 

[davemo888]

 pads are well worn in ( the way she drives  )

 and a big metal bar and plenty of grunt tells me all bushings are good too

 I'll check the lower ball joints on the morrow

    many thanks young mr Kernowman

Here to help   

Hope you find the fault..

By the way, is yours a 2wd or 4wd ?

i take it theres no abs on your bus.
Have you checked your rear brakes
would not have thought the master cylinder. thats more a case of no brakes or no assistance.
I would be thinking the discs warped only a fraction wouldnt show to the eye but would cause the problem on light braking like braking with a buckled wheel on a push bike.

Thanks Kernowman
 
 Its a 2w drive ..A 97 emina estima x(little scottish flag lower left hand corner ) tin top.

  Hello Tony
  there is abs,  believe it or not , haven't needed it since last christmas(2010) ..but it still works.
As for the discs ,I should get a new pair as they are farely cheep on ebay ,the ones on my bus are probably there
since japan ,...but they honestly look and feel ok .I will have to get them done though ,cause Lynn drives it most of the time
and its always a worry

[Kernowman]

You can get disc sets.. as you mentioned .. cheaply on ebay.
An easy job to do and a worthwhile for peace of mind.. 

[Kernowman]

There's a suitable set from autojap for 55.00 delivered.

[Kernowman]

Make sure you measure your disc to make sure they match the kit... there are several sizes.

[davemo888]

Thanks  Kernowman

  there the exact ones on my bus (and free brake pads as well)..nice .
 
  I'll email them tomorrow ..see if they deliver to Ireland.


       cheers    dave

[Kernowman]

They do deliver to outside UK.. but you will need to email for carriage price..

[davemo888]

Cheers mate

 thats good to know
 
    I will email them on the morrow

  you are a "star" and hopefully if I get across the pond to a meet,
 
 I will be purchasing copious amount of alchoholic beverages for yourself and the young mister Darbon

Now that one looks like you need some roughage  in your diet

Did you get the Juddering sorted Dave hows the bus running now

[davemo888]

Hi Tony

 haven't had a chance to to get discs yet , a bit strapped at the moment ,so we still have judder.
 but she passed the nct (mot) so it cant be serious just very annoying .
   had a scary moment with a pressurised expansion bottle and no heat ,but it turned out to
be the rubber seal on the stat was worn out and stuck,...one new toyota stat later problem solved phhew
othr than that shes running very well

                                                   

[flutered]

hi dave, pm me your location, we may be near one another.

[ADarbon]

good job you caught the pressure problem. do think the discs are warped then

[davemo888]

Hi Tony
     I would have to say yes , everything else has been checked .
2 tons of bus plus a full load would generate some heat when braking,and on these back roads we do some
serious braking.
    Looking at the discs ,they look origional (15 years old).So as soon as the minister of domestic and
financial affairs (wife)  gives me the go ahead (cash) I will buy new ones
