hi all, just trying to find out why my brand new wilwood calipers leak, ive had some hoses made by rally design and thay leak at both connections ,now i dont think its anythink to do with thw wilwoods , iv rang rally design and thay said its ok to put ptfe tape around them is it ok to put pluming tape around them or will the brake fluid rot the tape any advise, the car is a 1997 escort 1.8 si

thanks
andzz

 

there somthing wrong here just fitted my wilwoods lines by rally design and they dont leak

 

do you think thay have put the wrong size connecters on?

 

possible mate did you look at the ends to see if they were the right ones

 

what about the pfte tape, is it ok to use?

 

shouldny have to use tape surely? send them back if thats the only solution they give you

 

thanks all, will phone rally design up about this..

andzz

 

DONT USE PTFE TAPE

No way should you ever have to use PTFE thread tape on any brake connections What type of connections are they? Brake fittings seal on either copper crush washers or seats on the end of the pipe/fitting

I work for Goodridge by the way

 

willwoods have a tappered thread (1/8 NPT) into the caliper. your original brakes would have been M10x1 metric. make sure you have the correct fitting's/adapters

Also make sure you have the correct male/female connections matching on the nozzles of the pipe. i've seen them mismatch before causing leaks

I've had my wilwoods leak b4 when new however that was a from the crossover form one set of pistons to the other. was just a case of nipping up the 4 main bolts holding both sides together

 

This is the braided lines in question

 

Double post

 

Something dosent look right there

Is there a tapered seat at the bottom of the thread in the caliper (the seat should be same angle as on the fitting that srews into the caliper)

I'm not familiar with wilwoods but if its the way i think it is that copper washer on the caliper is doing fook all

 

looking at the pic the fitting setup is wrong , from the wilwood should be a double male , 1/8thnpt into the caliper then whatever thread you choose onto the other side of the double male - usually m10x1.0 iirc , then the brake line should fit straight onto this with no other joints washers nuts nor fook all , the outer end of the double male should be up against the olive in the brakeline and thats it - i make and have made all my lines for years - and they dont leak - ever

 

mine were leaking, had a bit of wear tho, 4-pots, just bought new ones and flogged the shagged ones (for repair) on e-bay for £80, sum guy with a Nova who was a bit handy had 'em, he was gonna use it for tracking

 

brake line is fitted the wrong way round the union into the caliper is wrong

mark you are bang on ive just fitted mine and what you say is what i got from rally design

 

Sorry I know Morto so its not a double post

That was the line rally design sent after it was quoted one was needed for a 1997 escort si with the wilwood midilite 4pot kit, the connector on the braided hose was not tapered but this one was



Does this mean that the adapter that was in the box should have been used ? the taper end into the caliper and the braided hose should have been a female connector that goes onto the adapter

 

on the hose the male end goes to brake line the female end goes on to adapter at caliper

 

Cheers Alan, this means the braided hose is wrong as my brake line end is a male connector

 

Yep it is

 

Cheers Mark

 

Getting new parts sent from Rally Design as like you said and we thought they were wrong
