Hard brake pedal

[del 172]

I’m planning on replacing discs and pads all round and the rear brake pipes,I’ve managed to get the o/s/r but no look with the n/s.however I’ve noticed when I press the pedal all feels ok and the brakes work fine,but if I go to press the pedal again it feels very hard and there’s little effort which can be concerning as I found out at Croft lol,any ideas ? Cheers

Have a look at the hard plastic vacuum line from the inlet manifold to the brake booster.

They can melt and collapse, giving you the symptoms you've described.

To answer your other point, one of the rear brake line pipes is no longer available from Renault.

I went for an aftermarket braided line instead, from Pro Line braided lines.

Yeah they said the n/s is no longer available so was thinking something like that.

It was around £50 for the pair.

It was around £50 for the pair.

Think the o/s was about £27

I meant the braided lines I bought 😅

I’ve checked the pipe,it’s been wrapped in foil and insulation tape as it’s looks to have melted,also not available from Renault.

Try and get one from a Renault Sport breaker like BTT Motorsport.

Thatll be the problem!

BTT should be able to help with the vacuum line.

If wanting to change/upgrade the brakes for track, send me a PM as I can supply various discs, pads, fluid, braided lines (kits and custom both Goodridge and Hel) , OE Renault brake lines etc etc

I’ve made a fresh pipe and rerouted it away from the manifold so shouldn’t have any more issues

 

[JamesBryan]

Wow that old one was bad!

Brakes should be a lot better now.
