Brakes are awful
 

hi guys

was wondering if there is a way to check the brake "bomb" on my audi ,

the brakes have never worked very well and need to be stood on for anything to happen, the discs and pads have plenty left on them too

thanks

Jim

Youre supposed to pump the pedal with the engine off and it should supply servo assistance for a certain number of depressions.
Should be on Phil Paynes isham research website.

welcome to the world of 1980's braking power. Mines pretty shit too but my benchmark for comparison is a 2007 Volvo and Volvo brakes do tend to stop you on a sixpence

at least 10 depressions with engine 'just turned off'

or full lock (if you have p.a.s.) and pump it with engine running.

if light comes on after 3 (all of mine do!:lol:) bad bomb

just get bigger legs..cheaper

so i should feel the pedal getting harder each time

no

10 with servo

then hard as a rock ( if its good)

or like mine

2/3 with servo

then hard as a rock:lol:

spot on , cheers mate, will try this tomorrow

No brake bomb on a Coupe GT

ah right,hmmmmm

well i will see what the servo does when i pump it anyway

I got a shock when I drove the 100 for the first time, they do need a good shove! big difference from the A6.

I have to be careful when i swap from the quattro into the Festa- I nearly go through the windscreen at first :lol:

True - vacuum reservoir. Your MityVac is your friend.

No they don't. The problem is a combination of reporting tolerance in the senders and ageing in all the components.

When you work through an ur-quattro or Type 44 braking system and restore EVERYTHING to nominal the brakes are excellent.

Most of the 'Porsche monoblock' and similar upgrades done to 1980s quattros are pointless Band-Aids to a sub-optimal braking system.

Main difference I found on my CQ was the following:

I changed all of the pads and disks and refurbed the callipers and the brakes were pretty rubbish even after all of that.

Next thing I did was change the brake flexible hoses, what a complete difference, firm pedal and much better braking efficiency, the car I think now stops as its intended to.

Overhauled the coupe brakes on my poor old gt and they were absolutely fine.
Never had any cause for concern with them.

hmmm, well i may invest in some new brake hoses then , no doubt they could do with being changed anyway tbh

This is true, I had my eyes opened up to this at Castle Combe this year, on track, in a quattro, with standard single pot brakes and uprated pads... It's braking ability was astonishingly good. competition standard almost.
