Evening all, been a while since I was on here, but i'm in need of the famous mud clubber advice!

Lately when in Landy i've noticed the brakes being a bit spongy on the first press, but then seem to be fine again on the second. Thought no more of it until once when braking i felt a slight judder through the pedel, pretty much like abs, but not as harsh. (it doesnt have abs before anyone suggests it!!)

I've tried the obvious solutions first such as looking for leaks, which there doesnt seem to be any of, though the fluid has gone down a mm or so, but that could just be through wear. The vacuum pipes seem in good condition, and tested the pump by having the pedal pressed when starting the engine. Even tried lamping on the brakes a few times, and everything seems to work and it skids to a halt in a straight line (well... straight enough for a landy on MT's! :roll: )

Only other thing ive noticed is when ive come to a standstill, I've literally stood on the pedal as hard as possible and where i would expect it to stop halfwayish when the pressure has built up, it seems to ever so slightly keep going, as if something is going somewhere...

Sorry for the long post, but hope someone could be of help as you usually are!

We tried allsorts as my 90 did this, in the end it was the front wheel bearings had so much wear in them it was pushing the pads back so it needed a double press if you hadnt braked for a while to get them working lol.

not sure if it will be the wheel bearings, as i've not long had them all changed, but i'll go and give them a wiggle if we get a dry night!

my wheel bearings are fine, (bar one) would that be it? surely not because of one small wheel bearing?

I guess it would depend on how much play there is in the bearing, ive had a pretty shot bearing before but not had this problem before!

Any other ideas guys?!

ill be interested in this as mine just started doing that over the last week, but aint had a looksy yet :roll:
1st press just a little bit at end of travle
2nd press through the windscreen :lol:
will have a look t morra if get time
as for now
i can only think of air in system ( somehow :roll: ...but is a landy)
or master cyl seals on way out.....but the pedal isnt creeping down, so that eliminated a leak anywhere and the master cyl seals :roll:

if ur running a disc rear axle i bet its the wheelbearings,

mine did the same but didnt have any play if u jacked the wheel up n checked for play,pulled the shaft out it & it was all over the shop

4 new wheel bearings & 2 stub axles later i had brakes again

extreme90 · « **Reply #8 on:** December 10, 2006, 22:34:15 »

now ino my fronts were running in mud last time i had a hub off :lol:
maily due to a broken shaft n i was rolling around in mud fixing it
1st port of call front bearings, she has got a nasy habbit l8ly of veering off to the left on her own :shock:
and that when it all started with the breaks :roll:

yeh, well i have drum rear brakes...
but on the pass. side rear the bearing is not too clever...

extreme90 · « **Reply #10 on:** December 10, 2006, 22:56:44 »

on the front its discs :lol:

indeed ! well done!

extreme90 · « **Reply #12 on:** December 10, 2006, 23:02:22 »

:lol: now now rob no need for sarcasm :lol:
sorry i couldnt resist
on a drum it wont make any difference as the springs will return the shoes back to the drum :roll:
in theory anyway :lol:
whats the front ones like ?
does the pedal creep down when pumped up hard ?

TDi90 · « **Reply #13 on:** December 10, 2006, 23:05:59 »

its exactly like urs. i depress the brake... and only brakes right down low, then up the brake and down again and i almost fly through the screen!

extreme90 · « **Reply #14 on:** December 10, 2006, 23:10:23 »

mine disk break rear :lol:

Adjust the brakes

racer was like that running a disk salsbury out back,fitted new shoes,modded the adjusters so they were adjusted up on the first notch & it had brilliant brakes

use the slightly smaller pedal to the right :P

Landy90IOM · « **Reply #19 on:** December 17, 2006, 15:30:48 »

what do ya know! Just had a wiggle of the front wheel, and a slight bit of wobble, so this might be the problem. Wouldnt have thought that would have caused it though, as i've had a bearing lubricated with water and parts of itself before, and never had the brake problem I have now...

Anyhoo, got a bearing on order, and i'll see if that solves the problem!

Cheers, guys

oh, by the way, did anyone else with the same braking problem find it to be the bearings?!

unknownmanxman · « **Reply #20 on:** December 17, 2006, 16:50:15 »

You know you could just tighten the bearing up a little?

After i refitted mine they seemed to take a while to 'bed-in' then tightened them up again..

I went through three sets of brake caliper-piston seals before i found out that my wheel bearing had play in it...

Your creeping pedal might suggest a failing master cylinder..

Landy90IOM · « **Reply #21 on:** December 17, 2006, 18:03:50 »

I am going to give it a nip once i find my hub spanner, and see what its like from there as wont have time to change it before the end of the year.

This is one of the first bearings i changed, and does seem to be a bit of water in there, so i will change it sometime. As for the master cylinder, well, i'll make sure its nothing else first

Heard anything from the biodiesel yet? Last time i rang him, he said you'd be the first to know. After using the bio from Laxey, i've noticed it waxes over very easily, someitmes around 5c, which is a real pain! I've reverted back to a mix of derv.

unknownmanxman · « **Reply #22 on:** December 17, 2006, 19:14:48 »

Lol.. he always says 'you'll be the first to know'. In reality, you have to ring him.

Yeah i knew it waxed in the winter, but i dont use it in the winter, only in the warmer part of the year..
Other than that is it going well for you?

Hub spanner?!?! cough cough, hammer and chisel! Lol..

i stand corrected, now founf the problem, drivers side hub wasnt running on bearings was running on a super friction free surface, called dust
was only checked last month :oops:
owells another stub axle bites the dust :roll:
