Reply With QuoteNice one Gary, will give that a go.
Thanks for the great tips, will let you know how it goes.
Cheers, Pete.

SupporterPeter, to firstly drain the reservoir I found thet disconnecting the low pressure hose on the pump end rather than the reservoir end gave me an easier way to drain the reservoir into a small measuring jug. When the jug starts to fill up put your thumb on the end of the hose to stem the flow of brake fluid whist you then empty the collected brake fluid into a larger container. ( I hopee that makes sense). Once the brake fluid is drained from the reservoir you can then gently lever it out of the modulator (it is a press fit into a rubber seal). The filter is part of the reservoir and cannot be removed for cleaning, but soaking the reservoir in a dish of warm soapy water will clean it up pretty well. Then rinse thoroughly and dry. I let mine dry in the sun for a day making sure it was free of any moisture.

SupporterPeter my brakes do the same thing, a slight wooshing noise, and the faster I press the brake pedal the more noticable it is.
My 93rrc did the same thing so I assumed it was normal. Both cars will pull up amazingly quick.

SupporterThanks Benji, yes that is exactly what mine does, otherwise the brakes a great.
I'd love to know what causes it, could be as simple as a few stray air bubbles in the system.
Mine is definitely doing it less after being bled, I'm hoping it's just another bleed.
Will let you know how it goes!
Thanks,
Pete.

SupporterI am the same I have the woosh sound. Also, I changed my modulator (with a non-new replacement) and it is still there. I figured that it was supposed to be like that.

SupporterPeter, I don't think cleaning the reservoir and filter will cure the whooshing sound but it will help your pump by not having to work as hard to pull the fluid through and of course less chance of contaminants in the system. My theory (and it is only a theory) is that the whooshing sound you are hearing is the rubber gaiter on the modulator. The linkage from the brake pedal to the modulator has a rubber gaiter on it and it may be that the shaft is sliding in and out of the gaiter producing a whooshing like sound......just a thought

SupporterThanks Gary, after having a close look at the braking system, I tend to agree with you, cleaning the modulator will probably not have any effect on the sound.
I had the same thought, as the pedal is connected to the modulator, I was suspecting something along those lines.
The brakes are working fine, so it's not really a safety issue, but it was getting a bit annoying having that sound every time I used the brake pedal.
Thanks for your thoughts on this.
Pete.
