<!--QuoteBegin-"mark"+--><div class='quotetop'>QUOTE("mark")</div><div class='quotemain'><!--QuoteEBegin-->I tried my much publicised big brake conversion on Dans car today!
<span style='font-size:21pt;line-height:100%'>IF you have a VT</span>
Cheap/Secondhand route, Parts used were:
Rover 623gsi single piston calipers
Rover ZS180 discs
623 pads
<span style='font-size:23pt;line-height:100%'><!--coloro:red--><span style="color:red"><!--/coloro-->
PLEASE CHECK THE ABOVE LIST - 623 DISKS DONT FIT<!--colorc--></span><!--/colorc--></span>
<span style='font-size:21pt;line-height:100%'>IF you have a VT and you are loaded (break 
)!!</span>
New MGZS180 calipers
New MGZS180 disks
New Pads
Total around £5/£600
<span style='font-size:25pt;line-height:100%'>IF you have a 16v</span>
Then you will require CRX Vtec front hubs AND Track Rod Ends as well. (this converts 16v front setup to match the VT). This is obviously in addition to the upgrade parts as listed above
The calipers are a perfect bolt on fit - but they sometimes need a 2mm spacer between the carrier and the caliper - this places the caliper in the correct position as the ZS discs have a 2mm difference in offset (VT's do not need this spacer only Rovers!)
The caliper itself needs a quick "clean" with an angle grinder - as the 623 discs are 2mm thinner than the ZS discs and WILL just "touch" if driven hard or overheated. Just take a very small amount from the caliper where the disk may contact.
This fits perfectly ! - and will fit under Rover 15" alloys with no clearance problems
The Calipers bolt up using the original bolts, and the ZS disks look much much bigger then the std items. As a bonus the 623 pads are much larger than the std CRX pads - so there is a much better surface area contacting the disk.
The 623 calipers work, as do the 620ti, some 620 autos come with the 282mm discs too - but I looked at 3 over the weekend - and they were all 262mm
BE SURE TO SPECIFY MGZS180 282mm Disks - as ZS120 disks are 262mm and are the same as the CRX VT
COSTS
Calipers S/H £30
Disks (new from Rover) £80 (this price has increased from £40 a pair since last year as Rover have seen the light
)
Brake fluid £3
new pads £10-£60
So anyone else for cheap decent brakes?
