big ives Posted March 18, 2010 Share Posted March 18, 2010 hi landy has just passed MOT brakes are good, however i want to upgrade the braking system on my 1996 300tdi defender which is used for offroad and on road i have been told to go for vented discs on the front and rear, is this ok for offroading? if i go vented, do i have to also change the brake calipers? what are the part numbers for the vented front and rear discs? any other suggestions for the brakes? many thanks Ivan Quote Link to comment Share on other sites More sharing options...
Lomenech Posted March 19, 2010 Share Posted March 19, 2010 just to let you know I have just ordered new calipers for my LR, same model and year, and with new pads as well the bill comes to 350, (same amount for new ones as trading in old ones for reconditioned), so if you don;t need to change the calipers then all the better!

Aragorn Posted March 19, 2010 Share Posted March 19, 2010 110's have vented fronts as standard, so fitting those is a reasonable first step, you will need a pair of calipers though as the disks are wider. 110 rears arent vented but the disks are slightly thicker and slightly larger. What exactly are you wanting to achieve from the "upgrade"? Fitting vented disks wont let you stop any quicker or make the brakes perform any better, all they will do is allow for better cooling of the disk, so when your working the brakes hard they wont overheat as quickly. I'd recommend giving the system an overhaul, new stainless braided lines, new fluid, and good quality pads will probably make a lot of difference if your existing setup is a bit tired.

mike4444244 Posted March 19, 2010 Share Posted March 19, 2010 Hi I'd look at whats wrong with your brakes first? A defender with standard discs all round should stop like its hit a brick wall! As above the vented discs are only an upgrade if you run into cooling probs eg lots of heavy towing in a hilly area... Stainless hoses are a good idea as they are fit and forget Mike Quote Link to comment Share on other sites More sharing options...
big ives Posted March 19, 2010 Author Share Posted March 19, 2010 many thanks for all the replys my 90 was a complete rebuild which i carried out myself and has stainless steel brake hoses, all new pipe pipes, good brake pads, and i think she stops good she past the MOT the other night and the MOT chap said the brakes where a bit ropey but didnt fail the 90 i was comparing the stopping against my Disco 2 Auto and my A6 Auto I was just checking to see if there was an upgrade but clearly i see i have nothing to worry about (need to stop being a Perfectionist) and YOU ALL have saved me a shed load of money and work thanks Quote Link to comment Share on other sites More sharing options...
white90 Posted March 19, 2010 Share Posted March 19, 2010 Plus a defender on larger than standard tyres the brakes on the MOT rolling road are not good the rears are especially bad. the brakes work fine but the grip n the rollers overcomes the brakes. Mine stops fine on the road but the MOT rollers it just about makes the grade I asked them to use the decellerometer<sp> this time which showed the brakes are ok Quote Link to comment Share on other sites More sharing options...

Retroanaconda Posted March 19, 2010 Share Posted March 19, 2010 Decellerometer is used for cars that cannot use a rolling road. I have my Defender done using it, don't like having it on the rolling road as the local MOT centre only has a 2WD one. Decellerometer is still valid for testing so it's no biggie.
