Hi,

Got my brake fluid replaced today. After getting in car the brake pedal was very soft !

It was nice and reactive/hard before this morning.

Before I go down tomorrow and complain, I think it's air ? I think they rushed it and never bled the air out ?. It's a 'quick' brand garage.

If I turn the car off, press the pedal 2 or 3 times, it hardens up. Under the LHS footwell it sounds like an air pump, never noticed that before.

Did they tell you they replaced the fluid? As its not normally included in a service

Brake fluid is scheduled to be changed every 2 years due to the fluid being 'hydroscopic', meaning, it absorbs moisture which causes the fluid to gradually degrade. (The exception to this is 'synthetic' brake fluid which is not hydroscopic).

It sounds to me that the system wasnt 'bled' properly as the pedal should have been at least as firm as it was before the work was done, if not firmer.
I would take the car back and ask them to bleed them again.......another explanation for a 'soft'ish' feel to the pedal would be if they fitted new brake pads at the same time which would require bedding in for a few miles after which the pedal becomes firm again.

it's not degrade, it just absorb moisture and then lowering the boiling point, azeotrope!

silicone brake fluid don't absorb moisture but it is immisible with water. once water get into the system then it will localized in the highest point which might cause corrosion. silicone fluid is hard to bleed, thick and also compressable.

btw all brake fluid is synthetic. glycol base (dot3,4 and 5.1) and silicone base dot5

and 206 can't use silicone brake fluid anyway....

I had this same problem after performing a service myself.... So I took it to a decent garage where I get any other work done usually and they did a pressure bleed on the system for £45, which sorted the problem Smile

If you are going to be picky........The word 'degrade' is used correctly in the context of describing brake fluid that is past its best!!.........


EBC, who are a respectable brake component supplier also use the word 'degrade' in their article covering the subject of brake fluid (as below).....perhaps you may want to email them and inform them that they are using an incorrect term!!



www.ebcbrakes.com/auto...ndex.shtml

Glycol fluids have a nasty characteristic of being “Hygroscopic” in that they attract and absorb water. This means that over the years the fluid in your vehicle system will degrade by the absorption of water. It is not uncommon to find glycol fluids containing up to 13 or 14% water which of course......(article continues)

Brake fluid should be changed every 2 years, helps stop the delicate hydraulic components from rusting internally due to the absorbed water content of the brake fluid.

A Gunson Easibleed makes bleeding the brakes much easier, if you use one of these remember 10 / 15 psi MAX in the tyre your using to provide the air for it else you will blow seals in the master cylinder!

Thanks all posters.

Brakes back to normal.

Took it back to the 'quick' garage, they bled the brakes in ten minutes, test drove it. They did not do that yesterday, if they did they would have found the problem. When I drove off today, brake pedal back to normal.

Local kids at my school say they put water in their trials (push) bikes. Corrosion !

I get a lot of wear on my brakes as I goto the Alps for hols, with a lot of kit.

To bleed my mountain bike hydraulic brakes, you just take a cap off which is on the handlebars, so the only place for air to go is out.
