Corsa Leak Driver Side

Pretty Pink

Hey Guys,

See alot of people asking about driver side leak so I thought I would share a link but I am not allowed (newbie)

Basically search Brake servo leak corsa there is a good website that shows a step by step on how to do it!

After reading it I am feeling brave enough to attempt it but the female in me is listing all the ways it could go so very wrong.

300 and up to get it fixed is complete madness!! I could do it my self the only issue I have is with sucking out most of the brake fluid, this is where I see my self crashing due to no brake fluid.

Does anyone know of a place in Tipperary/Waterford that does mechanic training or even a guy who loves working on cars? I really want to give it a lash and if I run in to difficulty I have a to go to person and I dont have 300 to hand over for a guy to slap on some sealant

Look up some youtube about brake bleeding.
As you will need to bled the brakes after master servo is replaced.

Im in dublin so too far away to assist but its a DIY job most with basic tools could undertake in their driveway.

You can use a turkey baster to suck out the brake fluid from reservior or open a caliper nipple at on wheel and bleed from there.

You will need a brake bleed kit, a cheap simple one will do the job mine was 5 euro from local motor factor. its just a clear rubber tube and plastic bottle but its served me well for a few years.

Not sure of the caliper nipple size I think its 8mm

Go over the step by step guide and make sure you have the correct tools.

Some of the fittings might be a bit tight if the car is old so spray them with WD40 or penetrating fluid a few times the day before you attempt it (avoid getting this any where near the friction surfaces / brake discs).

Having the correct size spanners will be important too as you don't want to round off any bolts. A small reasonable quality ratchet set will help too. If you want to do more work on cars all these tools will be used 100 times off, so always a good investment.

Bleeding the brakes will probably be a 2 person job so make sure you've got someone who can help during this. Also not sure what job your doing but be very careful jacking up the car and make sure to put additional measure in place before starting to work. If you are jacking the car up make sure its on a level / firm base (eg concrete) don't try this on gravel etc.. If you do take off a wheel always put it under the car so if something was to go wrong the car wouldn't drop to the ground.

Sounds good guys! gonna go down and ask the guys in the motor place and I know I will be asked a hundred questions when I mention brake fluid maybe I could tempt one with the promise of a cuppa

I love cars and have been out of the loop with cars and moved away from home so really lost but I think I can do this! I am delighted I asked tho because I could of attempted to do it then panicked when it got to the brake fluid bit and had no equipment fingers crossed

Hold on guys I think there is more to this query than meets the eye.

OP are you talking about a brake fluid leak or an air leak from the brake servo ? The former would mean currently your car is dangerous to drive so I wouldn't recommend anything but a tow truck.

However the latter is quite common on Corsa's, the symptom being a hissing sound constantly/occasionally from the brake pedal area.

The latter is an awkward job due to the location of the servo.

I have done this a few time and I really don't think it is a DIY job for someone who is not experienced.

Sorry but safety first. If you were near me I would gladly give a hand.

HI Mercmad, I had a look yesterday, I removed the battery, airfilter and windscreen water. The seal around the brake servo plate is really cracked... I rubbed alot of sealant around the seal but still leaking .. GRRR!!

I think its because I didnt remove the gasket (I wouldnt be confident removing that as its the brakes and brake fluid) and its difficult to get in around it and get to the underneath of it, even tho I brought my friend with the smallest hands with me and got them to rub the sealant to the underneath. The drip has reduced so I know I am in the right area there is just something small I am missing.

Mercmad, is it difficult to remove the gasket? I have looked in to getting the seal as I read you need to replace the small diamond shaped seal after each removal. I think I can send you a photo via PM to show the exact area if that would make for sense? I have "some" idea of what I am doing just dont have the terminology

Sorry for my late reply, hope not too late. Feel free to PM me or email the pictures, mercmad@gmail.com. Is it brake fluid that is leaking ? I understood, or assumed, it was brake servo pressure ? You said you saw a drip ? Presumably you wouldn't try to seal a brake fluid leak with sealant ? Maybe the pictures will explain.
