4 pots on classic question

[Grovit]

Have changed from 2 pots on the front to the 4 pots that were fitted on later model classics.

Am happy with the improved braking performance, and feel for the money this was a worthwhile conversion.

However - there has been a notable increase in brake pedal travel, before the brakes start to take effect.

As well as changing the calipers (and discs and pads) - goodridge braided lines have been fitted and new Motul dot 5.1 fluid has been applied.

I'm pretty confident that there isn't air in the system, as a fair bit of time was taken to make sure this wouldn't happen - also the brakes don't respond better after pumping the brake pedal and then braking (usual air in the system tell tell sign).

Does anyone have any ideas / suggestions at all - I can't see how by changing to 4 pots that there should be a greater level of brake pedal travel.

cheers folks

You can drive mine and see if there is any difference if you like.

Sounds like air in the system to me bud.

Have you checked for leaks in the calipers, especially around the dust seals?

As Dave says it's a classic sign of air in the system. It could also be boiled/tired fluid, but I wouldn't expect this if you've just flushed the system.

I must admit, I've never been impressed with the initial bite of the OE system. My Mum's 1 litre Kia puts you through the windscreen if you even look at the pedal. Mind you it's sh!t from anything about 30mph

If your still stuck, i have something else that can be used in the system which help's with the brake feel. £5 delivered and i'll let you know what they are and how to fit them.

Cheers for the comments chaps.

Ozzy, when you say leaks around the dust seals, I would assume the leaks would show up as leaking brake fluid - if so - nope there are no leaks. As we fitted new hoses all round, I've been double checking for leaks non stop and so far there haven't been any.

Dave (DRB5) - go on then, you've got my interest - what's this wunder cure you've got - pm me the details and I'll see if it's worth a fiver.

I'll maybe bleed through the system again, and if that dosen't work, Derek I might take you up on your offer !!

No problem Frank.

If you're going to bleed the brakes again, bleed the furthest away caliper first, then work your way towards the master cylinder.

Nice tip cheers -
