A while ago I posted that I was having brake problems; anyway all new pads fitted, new rear discs, calipers checked, lines checked etc etc, couldn't find a problem so narrowed it down to the ABS - drastic I know but I decided to bin the offending item and thanks to Stevefastbikes we got this cracked last weekend

Started by getting all of the bits together...




And then to start, rip out the pump




We thought this would be an afternoon's work having found a noddy guide that meant we'd need bend a couple of pipes, put some tees in and mount the bias valve under the bonnet. After some discussion we decided to do it properly so off to the near motor factor for a length of copper brake lines and lots of scrabbling around for spare unions, bolts etc and we ripped out all but one short length of the original line that ran through the bulkhead. The front and rear tees were mounted centrally to equalise pressure across the axel...




and then they were coupled to all new brake line running from the master cylinder...



to the wheels...





Clearly for the rear they had to go via a bias valve which we now decided to mount in the car but we couldn't decide where and eventually agreed on the seat mount - it is really conveniently position for easy adjustment whilst strapped-in





The copper lines are fine for now as the seat is fixed, but in due course I'm going to get some braided lines made up so I can fit the seat runners

When bleeding the brakes Steve noted how much the master cylinder was flexing the bulkhead so, thanks to KennyC, I now have a brake stopper. No slate on Kenny as it was brand new as he described, but the quality of the Tegiwa kit is quite poor with the welds coming away on one of the nuts, and TBH it's not the best quality weld.

But it's fitted...




With the complete bleed the brakes feel spot-on and much more direct now te ABS has gone, just need to look at ripping the loom out and sorting the dash light

Daft question - what does the brake stopper do??

And will be interested to hear your feedback on the brake bias valve, been thinking about one of them for a while now

JonMc

The brake stopper is fixed to the strut and then clamps to the end of the master cylinder - this should increase structural rigidity and reduce the bulk-head flex when you stamp on the stop pedal and therefore improve the pedal feel. Once the ABS was gone the pedal felt more positive anyway but I haven't been out since fitting the stopper. Can't say I've pushed the car to the limits to test the front to rear bias as I'm still bedding in the new pads and discs, but the main difference will be on track when I decide how much I want the rear to come around rather than follow the front when cornering

Nice work mate, need to have a look in your engine bay on Sunday to see how your fmic is fitted and what pipes go where

JonMc

iTrader: (51)

No worries mate, quite an easy job but needs patience

PS. removing the ABS makes more room for an induction kit

Is a Scooby better without abs then?

JonMc

iTrader: (51)

It all depends what you want it for - mine is predominantly a toy with a view to some track time and used on the road infrequently (when I get the right job again) so for me it's right and the brakes (Brembo upgrade to my WRX) feel more connected if you get my drift

Could have just pulled the fuse out.....

Nice work mate.

JonMc

iTrader: (51)

There's a fuse

Yea for the abs. I pull mine when on track

martin850

iTrader: (51)

A busy removing the abs fom my classic. Have you tested your set up yet if so how was it

mickywrx

iTrader: (29)

Should just pull the fuse, Mick. See how you get on without the ABS.

Mick T

It's also so we can fit the stoopid kn filter.

Don't forget, you want more rear bias in the wet (when on track)











Yes, really!

I've had it lock up once when a dozy cow in a 4x4 pulled out in front of me - pumped the brakes and all was well.

On some stretches of road where the ABS used to be quite intrusive because of the uneven surface and random ABS activation when hitting ripples in the road under braking has gone and I have much more confidence in the car at these points. There was enough weight transfer to trip the ABS but not to break traction so the braking is much more positive

Excellent work there john ,great detail too.

As mickywrx says pop the fuse first might have saved you a lots of work.

Great job.

Cheers Marty, it was a team effort with Stevefastbikes. A couple more bits to do which I'll be sorting next month when the car gets taxed and ready for its MOT
