Riot help

Hi all

Today I took delivery of a Riot SE 1.6

Capri front uprights
Fiesta front uprights upside down on the rear
Floor mount bias pedal box Mc .70 & .75

Overall it looks like a good car but the brakes are hugely over specced with Cosworth 4x4 discs front & rear with massive Brembo calipers on the front. The brakes work well enough but the pedal is long and quite soft. I figure this is due to a too small master cylinder for the size of the caliper.

I clearly don't need such big brakes in such a small car. They must weigh as much as me! I'm thinking of going for the hispec 245mm kit from Burton Power on the front https://www.burtonpower.com/hispec-4-pot-road-brake-kit-ford-escort-capri-245x20mm-hisk04e.html

On the rear there are spacers on the calipers again with massive Cosworth discs. I want to get rid of the spacers and go to standard discs.

Can anyone tell me what discs are used as standard on the rear?
What rear calipers are used as standard?
What are the ball joints used on the rear upright?

Finally it got quite hot when I took it out for 30 mins. When pushing on it got hot and cooled when cruising. It has a large Radtec rad so I guess that's ok. I wondered if there were any known issues running a Sigma in the middle? Weak water pump?

Thanks Rog

Welcomings.

What exactly do you mean by getting quite hot? You list your location as being up north and it isn't exactly tropical weather right now.

Presumably there is a water temperature gauge fitted but can you trust it? Do you know that the sender matches the gauge?
If the water boiled and/or was released from the header tank, assuming the cap is operating correctly, then there is a problem.

When driving ie car is moving, there is plenty of air going through the radiator to take away the heat. Generally cooling problems occur when stationary on a hot day.

You need to supply more information as to why think there is an issue.

Ive never come across a weak water pump, car engine designers know what they are doing, the pump may have a smaller diameter pulley, usually done for high revving engine, to reduce flow rate or the impeller blades are damage, not uncommon.

You need to remove the pump to be sure, would cost you the price of the gasket and buy a cheap temperature meter. You can put the thermocouple on the engine or even install the sender inside the water hose (kenlowe style) and check the temperature, cost is about a tenner.

One other thing to check that caused me to ponder for a while. my wife had a Reliant sports car and it was fine until pushed when the engine gauge showed it overheating - turned out that the previous owner had wired the fan the wrong way round so it lew the air back into the rad rather than pulling air through, wires swapped, problem cured

Well upon investigation it's a dodgy sensor. When the engine is cold the digidash is showing 85 degrees. New one ordered.

Hi i have a J15 but its the sameish under the skin
I run HISPEC Ultralite on the front with the Rally design VAG/Audi calipers on the rear they stop the car really well the IVA tester commented on how good the braking was at the test but it runs on the Caterham (triumph herald uprights front ?) and Sylvas own rear uprights sure the discs were 235mm solids on all 4 corners.
Havent tracked it yet but that is maybe were the small solid discs might suffer a bit

I have the Sigma 1.6se never had a problem with overheating etc is it all plumbed as per original Ford spec ? i have tried to vent the rear as much as poss with vents over the Cat and headers and with my clamshell a bit of ventilation holing on the ears next to me and passengers heads

Enjoy
