under heavy braking a high pitched squealing noise from under dash checked the threads here and found funkysi had same problem (funkysi when online can you tell me how you got it fixed) is it hard to fix or replace and were is it plus my brake warning light lights up when i brake no brake lights are out and brake fluid is full so is it related to the brake booster any advise welcome.

When you say no brake lights are out, how many do you have? You should have 2 on each side and also the spoiler light (not sure if this is monitored by that warning light though)

On mine the inner two brake lights had been disconnected and one used as a fog light, is yours similar?

all brake lights working thats both sides and spoiler, and as my z is a jdm I have a seperate fog light fitted so it is not wired into normal lights

I haven't fixed it yet. I will do in the spring. Car's garaged for the winter now. Snoopy wrote me a how2. I'll try and dig it up.

 

Unlike yours, I get no warning lights and my brakes actually feel very strong.

Found it!

 

1. Unbolt fluid reservoir from brake booster 12mm socket, (don’t touch any actual brake line fittings).

 

2. Remove vacuum pipe from front of the booster.

 

3. Now you'll need a pair of long nose pliers for this, Get your head under the dash you’re looking at the top of the brake pedal, you'll see a pin connecting the pedal and booster, you need to remove this pin. Using the long nose pliers remove the small spring clip holding the pin in place then slide the pin out.

 

4. Now you should see 2 bolts bolting the brake pedal bracket to the bulkhead remove these, 12mm socket required.

 

5. Now go back to the engine bay gently pull the brake reservoir away from the booster for clearance then move to one side being careful not to kink or damage the brake lines connected to it.

 

6. Now the brake booster should be loose and can now be removed.

 

7. Same procedure to refit.

great step by step instructions thank you funkysi. hope to fix this over christmass intresting to hear your brake warning light dose not come on as my booster has been making squealing noise for 3 to 4 weeks now and warning light has only just come on so not shure if related, give an update when fixed cheers mate

Mine's been making a noise for quite a while now. Hasn't really gotten any worse or effected the braking. It's just annoying.

Hi Jay thank you for the offer and hopfully I will get a good look at the booster this weeked to make shure it is at fault and if it is(sounds very possible) I will get in touch. ps how far away is button moon! cheers mate.

Plymouth m8 but i think the booster has been spoken for by FunkiSi now.....but ill keep in touch....

no probs posting to belfast could be expensive anyway and funkysi if you fit the booster in the near future let me now how you get on, cheers all

Yes posting ti to belfast would cost around £25 give or take IIRC....

I also have a spare booster from a 1993 TT Zed if any one interested;)

let you know ment and thanks for reply
