problems when lowered!!

[T.C cupra]

hi guys,

got the bezza lowered the other day by jabba sport and when i took it out last nite i was well impressed compared to standard mode.

but got a problem with the braking, under hard braking the rear is taking all the strain and after a spirited drive i noticed that the rear discs were glowing red..! pads had also taken a battering...

iv been told that this might be related to the braking bias which seems to be directing all the braking force to the rear. Im assuming this must be down to me lowering the car and the car thinking that the car is fully loaded with weight and is trying to even out the braking..? Anyway i can sort this out?

Iv been reading up on previous threads and noticed that people have dumped the standard ABS unit in favour of brake bias valves..? is this the best way to fix?

I would of thought Jabba would of said something about it unless even they dont know?

Sounds strange, i wouldnt have thought that lowering the car would affect the brake bias at all??!!

What suspension set up did you have fitted.

i've heard about this on peugeots etc with the torsion bar setup but never on anything else.

escort RST suffered from this problem when lowered something do to with the mechanical ABS (which was crap) when lowered the car thinks its fully laden, hit the brakes hard the back would step out ever so sllightly due to ABS only working on one rear wheel and oppisite front wheel (strange design) never heard of this on a ibiza maybe your caliper is fooked

my cars lowered and it sits lower than yours dude (as its only on standard wheels) and i have no problem, you think i might be to do with you replacing discs and pads and not calipers????

i had my car sittin -100 mm on koni coilovers (standard rims) and the only problem i had was with my exhaust hittin the back axle. oh and bein able 2 drive anywhere!!

The car thinks there is more weight on the rear when lowered due to it sitting lower, Lowering a car will be the only thing which will effect the brake bias...

FK Silverline X coilovers mate...

Dont think so, if anything the brake discs should be able to disperse the heat even better now they are drilled and grooved....

Its the ABS system which kicks in early locking the rear wheels, Ive read on here that people have got rid of the standard ABS system and fitted brake bias valves because of the piss poor ABS...

 

[Undezcupra]

might be worth asking seat if they have come accross it before then, and if it is to do with lowering surely the abs isnt piss poor? it wasnt designed for lowered suspension, iv never noticed the abs beeing crap, something to consider too would be to se if when jabba fitted the miltec they may have knocked or tampered with a brake line/cable/sensor???

 

[T.C cupra]

if it is to do with lowering surely the abs isnt piss poor? it wasnt designed for lowered suspension, iv never noticed the abs beeing crap

its designed to do the job of a brake bias valve and so should be able to do the job just as well, blatently isnt if its sending all the braking force to the back wheels. My car is about as low as a car which is fully loaded with passengers and full boot and full tank of fuel (gross weight) and should cope. If the car had a brake bias valve then there shouldent/wouldent be a problem...

Take a search of 'Brake Bias' and see what you find, many knowledgable people stating how bad the standard ABS system is.

tbh i'm not that familiar with underside of an Ibiza yet but when i owner Mk2 Golfs if they were lowered the brake compensater needed adjusting/slackening , i'm assuming Ibizas will have a similiar set-up ?

If i'm right , its easy enough , one bolt.

yes mate thats what i'm thinking, just need to buy a haynes manual to sort it out, i hope they come stanard on these cars if not it will be a pain to fit new one to the car and get rid of the ABS

anyone no where to get a haynes manual from as halfords dont sell the mk3 for some reason?

i've read on previous threads that someone has altered the brake bias valves on theres following the haynes manual, just need to pm the guy and find out what car hes got and how easy it is to do!!

oh well hope it sorted soon!!

thanks for all your help people

 

[Beaker™]

Haynes only do manuals for cars that have sold a certain amount. The mk3 is now out of production and obviously didnt hit haynes's magic number, so no manual.

Mines dropped to the floor and i've had no problem with brake bias at all btw.

The bias control is managed by the ABS....

If you feel the braking at the rear is "that much" (did I actually read "glowing red") - you need to work out this...

WHY AREN'T YOUR FRONT BRAKES WORKING

simple mechanical checks... are the lines buggered, the pads worn, the discs shot, the callipers ceased

yes mate rear discs where glowing

i have ebc discs and pads all round and everything was working fine before i lowered it

it's not like just one disc was lowing which would have been even worse it's both so it's got to be a brake bias valve or somthing!!

do they come standard on these cars?

 

[m0rk]

no!

it's all in the ABS system... the massive black thing with the brake pipes coming out of it in the engine bay.

lock the rears, ABS kicks in. crude, but effective ABS.

I am sure this is a mechanical thing, whether it's a blockage, or corrosion (happens more often than you'd think)

sorry i didnt realise you were so knowledgable i mean surely if you where then you wouldnt post up asking for help?



Only joking

anyway as regards to knowedgable people, there arent too many people as knowledgable as Mork when it comes to seats

 

[m0rk]

just one thought...

is it possible that the brake lines (at the front) are trapped in your new suspension? - that would reduce their efficiency?

They should have been secured

i didn't say i was clued up about it but thats just what i was told by a friend which made sense!!!!

dont no what your on about anyway cause you try and make out to me that you no everything when we go out but then i find you askin aload of questions on here!!!!!!!!!!!!!

oh rite i will have a look at that then mate

hopefull it won't be to expensive to sort out!

will let you no the outcome

thanks for the help mate, much appreciated
