Dispatch Brake Issue

[marmot]

Hi All new here looking for some help, I am not very technical and will try and describe the issues as best i can

 

I have a Dispatch 2011 (9 seater) and it has had on going break issue for nearly two year with no resolve, I am from the UK but now live in France

 

ok so April 2014 my van started making a squealing noise when breaking, i though it was the callipers so took it in to my local garage, when i went to collect it i was told it needed new pads and disc's all round, as soon as i picked it up it started squealing again, so back to the garage, it went back a few times but carried on making the noise, and it increased to squealing after i took my foot off the break peddle,

 

so i took it to my local Citroen garage, their first reaction was the other garage had put cheap pads and disc's on and they needed to bed in, i tried to tell them it was an issue from before but no luck, a few month later i took it back in and they decided to look at it, they claimed to have found a fault with the connector from the foot peddle to the servo, so replaced this, this still didn't fix it.

 

in november 2014 i returned to a wedding in the UK and took my van to a Citroen dealer there, they wanted to start replacing the fan belt???????

 

so took it to a mates garage, he said the breaks were binding but didn't know why, he replaced the hose from the servo, callipers and had to do disk's and pads as they had warped, this seamed to have worked for a while but the started again november 2015 and is getting worse again, with having no luck going to garages not sure where to turn to.

 

if it is hot day it is worse i am dreading summer time, also not sure if its relevant but a few times the clutch peddle has gone down and stayed down? and the electric window plays up with a mind of its own, i dont think these are related but four garages in i am will to think about any thing.

 

i would greatly appreciate and help or advice

Welcome to the forum.

 

If the brake squealing noise went when the pads/discs were replaced in November 2014 but it came back again in November 2015, then probably the brakes now need cleaning since the brake dust that builds up can cause the pads to seize in the calipers. The brakes should be cleaned every year or so depending on how many miles are covered each year. A service interval is not often given in the Maintenance and Warranty guides supplied by Citroen but if there was a Haynes manual it would say to clean them every 12 months as well as checking for wear.

 

If the clutch is hydraulically actuated then when the brake fluid is replaced every 2 years it should also be replaced in the clutch master and slave cylinders. So you could try bleeding the clutch cylinders since there could be a build up of dirt in them that is causing a piston in one to stick. It is also possible the return springs in the slave and master cylinders have worn and broken or maybe one of these cylinders has a worn seal and is leaking internally or externally.

A new brake master cylinder and brake fluid change should put this right
