Good news Jon,I did try and get them out when I refurbed them mate but they wouldn't budge,most brembo's/k-sports and AP's are all the same with that shim holding screw:brickwall
I would be thinking a blockage in the lines but the pistons all pushed back fine and pumped up again once I'd fitted the pads. Would air bubbles cause a problem and would bleeding be a worthwhile next step:wonder: |
Certainly worth a go mate,we have a VW polo in at the moment with a very very similar problem of O/S/F brake binding and we have almost eliminated everything except the ABS pump so you may need to be looking towards that having now eliminated the calipers and pads.

I will need to find someone local who can re-run the brake lines and tee together the front and rear pipes through an adjustable proportioning valve - removing the pump will also make more space for the induction kit:thumb:

That is my way of thinking as well in mine Jon,that and the fact it just looks plain ugly sat there:freak3:

Tbho I may just try and have a word with one of the ebay traders and have on of there's sent but with gift marked on it to save the tax etc??
|
I can't find the 'how-to' I was looking at a couple of months back but my thought is something like this one:wonder:
http://www.merlinmotorsport.co.uk/p3...a4a3d4244b333d I know you have to tee the fronts and rears together rather than have the four independant lines you have from the ABS pump, but iirc there's four lines in/out of the standard pump and only three into the one above:freak3: |
|
Bingo!!
I think I may as well just rip mine out as the engine bay is going to it's bare bones anyway! |
The brake pdf posted above also contains the non abs circuits

Time to break into the piggy-bank:eek: |
anyone local you could swap callipers with to test them to be 100%

I would defo be looking at the ABS Jon,it isn't the calipers and you have now eliminated the pads so it must be something in the system ie ABS pump/master cylinder.
|
Its worth changing the flexi hose as well. Ive had one colapse (not on a scooby) caused similar issues. The pressure from the pedal allowed fluid down to the caliper to apply the brakes, but wouldnt allow the fluid out so the brakes stayed slightly on. Then ofcourse that side got hot

The hoses are braided so they should not have collapsed and they appeared to be okay on a visual inspection:wonder:
Plus you can do your ABS delete and detail the job to which I can copy :lol1: |

Another very good point lol,it just keeps leading back to the ABS pump or master cylinder tbho mate.
Plus you can do your ABS delete and detail the job to which I can copy :lol1: The way I read it is you tee the fronts and rears together and use the valve to set the front/rear balance in the absence of the ABS pump - seems quite simple. Off to print the noddy guide and read it properly, good old night shifts:D |

I've PM'd one of the local members to help out with the delete - it's getting beyond my amatuer abilities and I don't have pipe-bending or flaring stuff. Found the Wilwood valve and some t-pieces on ebay for about £60 all in.

Have you got a link for the wilwood valve and t-piece's mate and yes I would be more looking towards the ABS than master cylinder for the problem:)

I am set on deleting mine now:thumb: http://www.ebay.co.uk/itm/3603921223...#ht_1083wt_906 and one of these... http://www.ebay.co.uk/itm/WILWOOD-26...ht_1480wt_1111 I read up on it last night and the job is simple: Tee the 2 front lines together and connect to one output from the master cylinder. Tee the 2 rear lines together and connect to the bias valve. Connect the bias valve to the second output from the master cylinder. Adjust bias valve so the back brakes lock up first for serious tail out action:D |

Only one of the unions on my ABS pump is seized so I should have enough unions and pipe to recycle it - and no, the seized one is not the O/S/F either, that would have been too simple:wonder:

Postman arrived today so I just need the garage to let me know when is good to run along so we can bend and flare all the pipes to suit:norty:
Need to do a steady couple more runs to work and back at the current rate though:eek: I can't think of anything else as a block in the pipe would not allow the pistons to push out as well as retract, all the pistons are free and move when the pedal is pumped, and the only part that is channel specific is the ABS pump - hopefully I'll be happy again soon... http://img.photobucket.com/albums/v5...6/IMG_0519.jpg Also had these turn up from CRN today ready to replace my rather sorry looking rear OE discs:D http://img.photobucket.com/albums/v5...6/IMG_0520.jpg I can then get my Brembo HP sport rear pads fitted and the brakes should be all done:thumb: |
Not hanging about there Jon,good man:thumb:
|
Can't afford to mate - even been toying with buying my own brake flaring kit and pipe bender but I still need to get on the ramps so I can drop all four wheels off and bleed the brakes:D
|
I can't wait to ditch my ABS and have a much cleaner inner wing area on that side!
It will be good to see what your feelings are on the brakes after removal as well! |
