Just fitted the drivers side recirc valve this afternoon, couldn't be arsed to do the other one as the rear bolt was harder to get to.

 

Took the car out for a blast afterwards so make sure everything was ok.

 

When I got back I washed the car, and fook me - chucked some water at the front wheels and it literally boiled off! :eek: Didnt think the brakes would get that hot! It was the hubs actually where the water was boiling!

 

Goosehonk hasnt gone though :rolleyes: So I will have to fit the pass side recirc valve.

u sure theyre not sticking? your brakes i mean! ive had this on previous cars. Jack it up see if the wheel spins free

Dunno, they could be :confused: Although I had the caliper seal kit fitted in Sept. Will do anyway mate cheers :)

brakes get very very hot, easily hot enough to boil water!!

 

just try doing pads & discs after someone has just drove it to you!! :mad:

Down from 100kmh to nothing means shedding 580kJ of kinetic energy somewhere - suppose you stop in 10 seconds, that's 58kW.

 

Suppose 20% goes into the drivetrain, leaves 45 ish. Suppose 80/20 front/rear - the fronts are dissipating heat at 18kW per side. No wonder they get hot.

 

If someone can find out the specific heat of discs and pads we could work out exactly how hot...

 

Or think of it the other way - it takes 280 horses at the fly to get to 60 in 5.5 seconds, so you must get 280 horses of heating when stopping from 60 in 5.5 seconds. (Which ties up with my maths above, luckily. ;) )

NO BLOODY MATH. I have enough to do at UNI

Hard to believe I left uni because there was too much maths innit?

 

Here's a hint, avoid the discussion on injector fuelling elsewhere in this forum!

Damn you really need to get out more :rolleyes: :tongue:

Here here.

 

Best way to check if your brakes are working ok is. Go for a good blast, giving it some heavy braking then as soon as you stop. Get out of the car and using your fingers feel and see how sharp the ridges are on the disc's before they cool.

LOL even that doesn't help, one of the guys I drink with has been rallying for 30 years or so...

He was my cure for sticky breaks. I put some springs to hold back the calipers as they were binding just slightly even after being sefitted. worked a treat. Then I just bought some stillen from mike and they work a treat and look the badgers nadgers
